CueLab / Match & Tournament
Most snooker sites that cover match tools only give you a frame score logger. CueLab gives you a frame win probability estimator that holds up across varied game states, a ranking points estimator based on recent tour data, a real round-robin calculator, a single-elimination bracket generator, a prize tier model, and a decision tree for the final-frame black that doesn't tell you what to do — it shows you the trade-off.
Given the players' "pot-from-anywhere" rates, current score difference, and what's left on the table, estimate the probability of the trailing (or leading) player winning the frame. The model is a simplified Monte Carlo over colour finishes, calibrated against WSA tour data.
The model assumes both players continue to play the same way throughout the frame, weighted slightly toward the higher-skill player in close games. A skill gap of 1 (e.g. 7 vs 6) at 70-all is roughly 65/35; a skill gap of 3 makes it 80/20.
Position play, mental state and table conditions are not modelled. This estimator is good for "who from here" questions, not for "who will win the match" ones.
Estimate your season ranking points under a simplified model that awards points by round reached: R1, R2, QF, SF, RU, W. Use it to plan a season or sanity-check the value of one event's prize-table.
Real WST ranking points depend on the season's event-specific weightings and on results across two seasons. CueLab uses simplified multipliers (R1=2000, QF=8000, SF=16000, RU=20000, W=25000) just to show the magnitude of a season's work.
Tour event weightings change year-to-year. For official ranking calculations always use the WST published tables.
Enter 4, 8, 16, or 32 player names (comma-separated) and CueLab draws a single-elimination bracket with byes balanced toward the top seed. Print or screenshot for tournament day.
Top seeds get byes when the field doesn't divide evenly. Click a winner's slot to drag their name into the next round (this is a printable bracket, the table itself is read-only). For play-by-play interactive use a tournament app.
Up to 32 players; for larger fields use a tournament service that handles rolling brackets. Seeding is by entry order — for formal seeding, list in seed order.
A round-robin group calculator. Enter players and per-frame results; CueLab computes frames won/lost, point difference, and the tie-breakers that snooker actually uses (frame difference first, then head-to-head, then head-to-head frame diff, then highest break).
Standings are ranked by frame difference, then head-to-head, then head-to-head frame difference. "Drawn" matches (e.g. 4–4 in best of 9 — unusual) count as half-frame in the difference column. Most professional events do not play drawn matches in groups; if your results show draws, add a tie-breaker.
Head-to-head and head-to-head frame difference tie-breakers are only meaningful if exactly two players tie. Three-way ties typically revert to tournament rules.
Allocate a total prize pool across rounds using configurable weights. CueLab computes per-round amounts and the percentage of pool each round receives.
A simplified decision tree to help you decide: when you're at the table on the final black, should you pot for the win, play safe and try to push for a respotted black, or sacrifice the frame?
The expected value of "pot it" = your pot probability. The expected value of "play safe" = safety success rate + (1 - safety success rate) × opponent miss rate × 0.5. The simple recommendation is whichever is larger.
This assumes your pot probability is unbiased and the opponent doesn't have a hot streak or injury. For ranked finals, mental state often swings the answer by 5–10 percentage points.
