1. The league is intended for amateur players. Players registered with the Czech Squash Association (ČASQ) are only accepted if they had already participated in the SCE League before becoming registered. New ČASQ players may join the SCE League only if their current ČASQ ranking is above 60 for men or above 30 for women. The league is mixed and open to both men and women.
2. The entry fee is 400 CZK and must be paid at the SCE reception before a player’s first league match. After payment, players will receive a password granting access to the results database. An exception applies to players who registered for one of the last two rounds of the previous season and paid the increased entry fee of  400 CZK  these players have already covered the fee for the new season and only need to collect their login password at the SCE reception. After paying the entry fee, players are required to register without delay in the SCE Squash League player database.
   If a player fails to meet these requirements by the end of the round in which they began participating, they may be removed from the league.
3. Placement into individual groups for round 1 of the new league season is based on the results of the final round of the previous season. New players are placed in the lowest group or with a wild card (WC) in higher group (see wild card rule). The same applies to players who register later during the season.
4. League is devided into groups, usually made out of 5 players. If a player enters a group with a wild card (WC), the group may have 6 players. The number of players may also vary in the lowest groups, with a minimum of 3 and a maximum of 7 players.
5. Every round of the league is played over approximately one month. The exact start and end dates of each round are always announced on the website www.sceliga.cz and are binding. Once a round is closed, results can no longer be entered into the database (with the exception of rare and justified cases approved by the league coordinator). The league consists of 10 rounds in total (January to November, with July and August combined into one round). No regular round is played in December, instead, a final tournament is held – see point 19.
6. Players arrange match dates themselves using the phone or email contacts available in the player database. Each player is responsible for actively reaching out to their group opponents as soon as possible to schedule matches. A match invitation must be sent no later than 10 days before the round deadline. The opponent must respond to the invitation no later than 5 days before the deadline, otherwise the inviting player may record a default win in their favour.
7. An agreed match date is binding. In justified cases, it may be cancelled no later than 24 hours in advance, either by phone or text message. If a player fails to appear for a match without proper notice, the match will be forfeited and they must pay the court fee during their next visit to SCE. Failure to fulfil this obligation may result in expulsion from the league. The same applies if players reserve a court for a league match and allow the booking to lapse without cancellation in such cases, each player must pay 50% of the unused court fee. If a player cancels a scheduled match in time, they are required to propose a suitable alternative date to their opponent. Otherwise, the match may be forfeited in favour of the opponent. If the originally agreed match date falls within the final 7 days of the round, the opponent is not obliged to accept a rescheduled date and may claim a forfeit win.
8. All league matches must be played on SCE courts, with a 15% discount on the current price (this discount does not apply in cases of unused reservations – see point 7). Exceptions may be granted in justified cases by the league coordinator. Matches are played according to official international squash rules, with the current modifications applied to men's competitions by the ČASQ - i.e. matches are played as best of five sets, each set goes to 11 points, with a minimum two-point difference. The official ball is the Dunlop double yellow dot (or an equivalent ball of another brand). Players may agree to use a different ball. Matches are self-officiated by the players, or they may agree on a referee, whose decisions must be respected.
9. Unfinished matches due to time constraints or other reasons may, by mutual agreement, either be completed later or the partial score counted. In case of disagreement between opponents, preference is given to completing the match. If a player forfeits during a match, the retiring player is credited with the number of sets they had won up to the moment of forfeiture (e.g., 1:3 if the score was 1:1 at the time of forfeiture and the third set was in progress).
10. Match results (only the set scores, not the individual game points within each set) must be entered into the online results database, which is accessible to all players after entering a login password (each player has access only to enter their own results for the current round).The winner of the match is obliged to enter the result unless both players agree otherwise; the opponent does not have to confirm the result. Forfeited matches must also be recorded in the database — it is important to distinguish a result of 3:S (in case of a forfeit) from 3:0 (in case of a completed match). If any results are not entered by the round deadline, they will automatically be recorded as a double forfeit. In case of protests regarding an entered result or forfeit, the competition supervisor must be contacted no later than 2 days after the round deadline. However, any change to the entered result must be confirmed by both players to avoid further discrepancies. The competition supervisor or an authorized representative (e.g., an SCE employee) has the right to perform random checks to verify that recorded matches were indeed played.
11. In the group table, each player is awarded 3 points for a win, 1 point for a loss, and 0 points for a forfeited match. Forfeited matches are recorded with a score of 3:0 in case of a one-sided forfeit, or 0:0 in case of a double forfeit.
12. At the end of the round, the group ranking is determined based on the following criteria::
    1. Total number of points
    2. Head-to-head match(es) (or a mini-table of mutual matches among three or more players) – number of wins, and if necessary, set difference
    3. Overall set difference from all matches in the group
    4. Player’s ranking in the previous round of the competition (in case of a tie in the three criteria above, the player ranked lower in the previous round is placed higher in the current round)
13. After the round ends, players receive points for the overall league ranking based on their group placement as follows: the player in last place in the lowest league receives 1 point, the second-to-last player in the lowest league receives 2 points, and so on up to the first-place player in the 1st league (who receives as many points as there are total players). Additionally, the top three players in the 1st league receive bonus points of 3, 2, and 1, respectively. A player who does not play any matches during the round (i.e., has 0 points in the group table) receives half the points they would be entitled to based on their placement (rounded up to the nearest whole number). A wildcard player who finishes 3rd or lower in their group does not receive points for that round. A wildcard player who finishes 3rd or lower in their group does not receive points for that round. The overall league ranking is determined by the sum of points earned across all 10 league rounds plus the final tournament — see point 20 for details.
14. A player who fails to play any matches in two consecutive league rounds and does not inform the competition supervisor of their intention to participate in the next round will be automatically removed from the league. They may request re-entry into the league at any time, either into the last group or, by discretionary decision, into a higher group.
15. If there is no player with a wildcard (DK) in any group, promotion and relegation between groups are as follows: the top two players in the group standings move up one group (except for the 1st league, which has no promotion), and the bottom two players move down one group. If more than two players in a group fail to play any matches, all such players are relegated one group down, and the corresponding number of players from the lower group are promoted. If a player withdraws from the competition or is removed due to missing matches in two consecutive rounds, one fewer player is relegated from the lower group to maintain a consistent group size of five players. Promotion and relegation involving players with wildcards (DK) are handled separately (see below). In general, only the group winner is entitled to promotion to a higher group; the second-placed player may be promoted only if the rules concerning wildcard players do not apply.
16. After the round deadline, the final results for each group are automatically generated, with any missing results recorded as double forfeits. Any protests must be submitted to the competition supervisor within three days after the round deadline. In case of disputes, the competition supervisor has the authority to decide after hearing both parties. Once the protest period has expired, the results will be declared final, and updated tables for the next round will be published.
17. A wildcard (DK) can be requested by any new player or by a player who was removed from the competition under Rule 14 (due to missing all matches in two consecutive rounds). However, such a player may only request a wildcard up to the group from which they were removed. A maximum of two players can be granted wildcards per month, with only one wildcard player allowed per group. If more players apply for a wildcard in a particular group, priority is given to earlier applications. If there are more than two wildcard applicants, priority is again given to earlier applications; the others must either start in the lowest group or wait for the next league round. Each player may request a wildcard only once during the competition season (exceptions may be granted by the competition supervisor, e.g., for players who interrupted participation for health reasons). Multiple wildcard players may also be placed in the 1st and 2nd league rounds (applicable only to new league entrants). A player already participating in the league may also request a wildcard once per season; these wildcards are granted only if there are no more than two wildcard applicants from new players or those removed under Rule 14.
18. The following special rules apply to players with wildcard (DK) status who participated in the given round:
    
    • If a player with wildcard (DK) status wins their group, they are promoted to a higher group. Along with them, the next best-placed player is also promoted; however, this does not apply if there are multiple DK players in the higher groups—in that case, only the winner is promoted. Two players finishing in 5th and 6th place are relegated to the lower group, and only the winner of the lower group with DK status is promoted, adjusting the group size to five players. The same procedure applies to subsequent lower groups to maintain a group size of five players (exceptions may occur if a player withdraws from the competition in any of the lower groups or the DK group). If there are multiple DK players in the higher groups, up to three lowest-ranked players from lower groups may be relegated.
    • If a player with wildcard (DK) status finishes 2nd in their group, they remain in that group. Players finishing 1st and 3rd in the group are promoted to the higher group, while only the winner of the lower group is promoted to this group, and the same applies to lower groups to maintain five players per group. Exceptions may occur with a higher number of DK players or if some players withdraw; handling such exceptions is at the discretion of the competition supervisor, but the rule that the group winner has the right to promotion to the higher group must always be respected.
    • If a player with wildcard (DK) status finishes 3rd place or lower in their group, they are relegated to the last group. If this player has previously participated in the league, they are relegated two groups lower than the group from which they requested the DK status—in that group, they retain the DK status in the next round and the same rules apply to them. Promotion and relegation between groups in this case follow the standard procedures (as described above).

An exception to these rules may be granted by the competition supervisor, for example, if a spot opens up in another league group (generally lower than the group where the DK player previously competed).

1. At the end of the competition season (in December), a final tournament will be held. This tournament will be organized in two categories:
   
   • Masters Category: The right to compete in this category is granted to the top eight players in the overall standings after 12 league rounds. If any of these players do not participate, their spot is passed to the next player in the standings, or the organizer may fill the total of eight players with a wildcard entry. The competition is played in two groups of four players each (Group A: 1st, 4th, 5th, 8th; Group B: 2nd, 3rd, 6th, 7th in the overall standings) in a round-robin format, followed by semifinals, finals, and placement matches (cross matches based on group rankings). All matches except the final are played as best-of-three sets (first to 2 sets wins), while the final is played as best-of-five sets (first to 3 sets wins).
   • Open Category: This category is open to the other league players and potentially other players (with an increased entry fee). The format of this category will be determined by the organizer based on the number of participants; it may be played either in groups or in a knockout system with a consolation bracket

The tournament entry fee is 200 CZK for league players and 300 CZK for other participants (who may only compete in Category B)

1. Points toward the overall squash league ranking will be awarded for placements in the Masters tournament as follows:
