APA vs BCA vs WPA Rules: Which Rulebook Governs Your League Night
Call shot or slop? Ball in hand or the kitchen? The answer changes with the rulebook your league plays under — and the differences are bigger than most players think.
Walk into almost any poolroom on league night and you will hear the same argument: "That's not a foul where I play." Usually both players are right — they are just playing under different rulebooks. Three rule systems cover most organized 8-ball in North America: the WPA Rules of Play (the international standard behind pro events), the BCAPL rulebook used by BCA Pool League, and the APA's own ruleset, built around its handicapped format. The games look identical; the details are not.
Which rulebook does your league actually use?
- APA (American Poolplayers Association): the largest amateur pool league in the world. Its rules live in the team manual and at rules.poolplayers.com, and they are tuned for handicapped play. Local bylaws can add twists on top.
- BCAPL (BCA Pool League): run by CueSports International under the Billiard Congress of America umbrella — a call-shot rulebook written for league play.
- WPA (World Pool Association): the Rules of Play behind events like the World Pool Championship. Many independent leagues adopt WPA rules outright, sometimes with house modifications.
The table below shows where the three books genuinely disagree on 8-ball.
| Flashpoint | APA | BCAPL | WPA |
|---|---|---|---|
| Call shot? | No — slop counts | Yes | Yes |
| 8-ball on the break | Win (loss if the cue ball fouls) | Not a win | Not a win |
| Foul on the break | Ball in hand behind the head string | Ball in hand anywhere | Table as-is, or ball in hand behind the head string |
| Regular foul penalty | Ball in hand anywhere | Ball in hand anywhere | Ball in hand anywhere |
| Jump cues | Masters divisions only | Legal (40" minimum) | Legal (40" minimum) |
| Push-out (9-ball) | Not in handicapped play | Legal | Legal |
Is slop really legal in APA?
Yes — this is the single biggest culture shock. APA 8-ball is not a call-shot game: any ball you pocket without fouling counts, and you keep shooting even if it rattles in off three cushions. The only shot that must be designated is the 8-ball, which has to drop in a marked pocket — a coaster or similar marker placed next to it.
Two consequences follow. There is no "safety call," so a legally pocketed ball always continues your inning — you cannot make a ball and pass the table. And the marker matters: pocket the 8 in an unmarked pocket and it is a loss of game if the opponent calls it.
BCAPL and WPA both play call shot. Obvious shots need no call, but anything disputable must be designated, and a ball pocketed uncalled simply ends your inning — it stays down. More on calling, slop and the rack in Call Shots, Slop and Racking Rules.
What happens when the 8-ball falls on the break?
- APA: a win — but if the cue ball scratches or leaves the table on the same break, it is a loss.
- BCAPL: not a win. With no foul, the breaker spots the 8 and continues, or re-racks and breaks again. With a foul, the opponent chooses between spotting the 8 and taking ball in hand, or re-racking.
- WPA: not a win. The breaker re-spots the 8 and accepts the table, or re-breaks. If the break also scratched, the opponent may spot the 8 and take ball in hand behind the head string, or re-break.
All three define a legal break the same way — pocket a ball or drive at least four object balls to a rail. APA adds one condition: the cue ball must strike the head ball or a ball in the second row first.
Is it ball in hand or ball behind the line?
After a foul on the break, the books split again:
- APA: ball in hand behind the head string — the "kitchen" — and the first contact must be an object ball outside the head string. A ball on the line or past it is playable; a ball inside it is not.
- WPA: the incoming player accepts the table in position or takes ball in hand behind the head string.
- BCAPL: ball in hand anywhere on the table — the most generous of the three.
Once the break is over, all three agree: a standard foul gives the opponent ball in hand anywhere on the playing surface.
Do the foul lists match?
Mostly. Scratching, hitting the wrong ball first, failing to reach a rail after contact, knocking a ball off the table, double hits and push shots are fouls everywhere — as is scooping under the cue ball to jump it, since a legal jump is struck down through the ball. The full rundown is in Pool Fouls Explained, but a few quirks are league-specific:
- APA uses a closed foul list. Anything not on it is a "sportsmanship violation," not a ball-in-hand foul — and taking strategy advice from anyone but your designated coach is itself a foul. Uniquely, APA counts a scratch (or cue ball off the table) while shooting the 8-ball as a loss of game even when the 8 stays down; under BCAPL and WPA that same scratch is only a foul.
- Equipment: APA restricts jump cues to Masters divisions, though a regular shooting cue may perform jump shots in every division and a break cue may only break. BCAPL and WPA allow jump cues of at least 40 inches.
- Push-outs: standard in WPA-rules 9-ball and legal in BCAPL, but banned in APA's handicapped formats; APA Masters divisions follow U.S. Amateur Championship rules and allow it.
How do you check the rules before league night?
A five-minute routine kills most arguments:
- Ask which book you are under — APA, BCAPL, WPA-based house rules, or a custom sheet. For APA, ask for the local bylaws too; league management can adjust details.
- Settle three questions before the lag: does the 8 on the break win, is it call shot or slop, and after a break scratch is it the kitchen or anywhere?
- Know your format's quirks — APA players need a pocket marker, and the Equalizer handicap shapes the whole match; see How APA Skill Levels Work.
- Bookmark the sources — the APA rules site, the BCAPL rulebook from CueSports International, and the WPA Rules of Play are all free to read. A saved copy settles disputes faster than memory.
- Keep the quick reference handy — our Pool Rules Quick Reference and the 8-Ball Rules guide cover the game-by-game details.

Is the 8-ball on the break a win in APA?
Yes — unless the cue ball scratches or leaves the table on the same break, in which case it is a loss of game. Under BCAPL and WPA rules, the 8 on the break is never an automatic win.
Does APA 8-ball use call shot?
No. You do not call balls or pockets; any ball legally pocketed counts. The only designated shot is the 8-ball, which must go into a marked pocket.
Is scratching on the 8-ball an automatic loss?
Only in APA — a cue-ball scratch or a cue ball knocked off the table while shooting the 8 loses the game, and merely missing the 8 entirely (a "table scratch") is just a foul. Under BCAPL and WPA rules, scratching on the 8 is only a foul unless the 8-ball is also pocketed.
Where do you get ball in hand after a break scratch?
APA and WPA put the cue ball behind the head string (APA also requires the first contact to be a ball outside the line); BCAPL gives ball in hand anywhere on the table.
Where can I read the official rules?
APA publishes its rules at rules.poolplayers.com, the BCAPL rulebook is available through CueSports International at playcsipool.com, and the WPA Rules of Play are at wpapool.com/rules/.
