PachinkoMaster is a free, browser-based random decision maker powered by real physics. Drop balls through a grid of pegs and let the laws of physics decide your outcome — no hidden algorithm, no weighted results. What you see is what you get.
Each ball dropped from the top of the board collides with pegs and deflects unpredictably left or right, eventually landing in one of the prize slots at the bottom. Because the physics are simulated with real-world accuracy, tiny differences in starting position lead to completely different outcomes on every drop. The result is genuinely random and visually transparent.
PachinkoMaster is used by families settling dinner debates, offices running team tournaments, teachers picking students randomly in the classroom, streamers running live viewer giveaways, fantasy sports leagues drawing draft orders, and anyone who needs a fair, fun, visually satisfying way to make a random decision.
The knockout mode lets you run a proper seeded bracket tournament with up to 200 players. A qualifying round ranks all players by score, then the top players — in bracket sizes of 2, 4, 8, 16, 32, 64 or 128 — compete head-to-head in a single-elimination bracket until one champion remains. A full visual bracket shows every match and result. This is the same format used in the FIFA World Cup, Wimbledon, and most major knockout competitions.
