The Basic Rules of Plinko
Every ball takes twelve independent fair left/right bounces. Add its side position after every row in the selected window. The square of that sum prices the return. The thirteen landing lanes show where the ball ends; they are not payout slots.
Listening Windows and Payouts
Attack adds side positions after rows 1–6; Tail adds them after rows 7–12; Whole adds them after all twelve rows. Each left bounce changes position by −1 and each right bounce by +1. Positive and negative exposure of equal magnitude receive the same factor. For example, six early left bounces in Attack give positions −1,−2,−3,−4,−5,−6 and exposure −21. A 20-coin stake then returns approximately 93.046153 coins before whole-coin settlement.
The Math: House Edge and RTP
The factor is 0.96 × exposure² divided by 91, 307 or 650 for Attack, Tail or Whole. Enumeration of all 4096 equally likely paths gives exact return 96% in every window. This is a long-run mathematical average, not a promised result for a session. Changing the listening window changes the path statistic, not the probability of a left or right bounce. Previous results do not affect a fresh ball.
Why Use the Free Demo First?
Each ball captures its stake and listening window. Up to six may fall together. Window and stake changes are locked during flight; restoring the wallet is blocked until all balls settle. The demo has no timed betting requirement or prize. The wallet starts at 1000 free coins and stores its balance and fractional returns in localStorage in this browser. Refreshing preserves settled balance. Restore sets a low balance to 1000; it does not add 1000. Clearing this site’s stored data starts a fresh wallet. Balances are not synchronised across devices.
Setting Limits for Responsible Play
Set a time boundary and stop when you choose. The demo has no financial rewards and does not predict commercial game outcomes. Chasing losses does not change its expected return.
Frequently asked questions
Can I predict where the ball will land in Plinko?
Previous results cannot predict a fresh path. Each of its twelve bounces has left/right probability one half.
Does the demo game use the same odds as the real money game?
Path Exposure Plinko is an independently designed browser demo, not a copy or certification of a commercial game. Virtual coins cannot be bought, withdrawn or redeemed for prizes.
What is the difference between the three listening windows?
Attack adds side positions after rows 1–6; Tail adds them after rows 7–12; Whole adds them after all twelve rows. Each left bounce changes position by −1 and each right bounce by +1. Positive and negative exposure of equal magnitude receive the same factor.
What return has been verified for this demo?
The factor is 0.96 × exposure² divided by 91, 307 or 650 for Attack, Tail or Whole. Enumeration of all 4096 equally likely paths gives exact return 96% in every window. This is a long-run mathematical average, not a promised result for a session.
