02The game
How it plays, and where it fits.
The game
- What the player does
- The player sets 8 to 16 rows of pegs and drops each chip with one of three buttons, low, medium or high risk; it goes left or right at every row into a bucket that pays its multiplier in that risk’s table.
- Why players come back
- The plinko players already know, with exact maths: every one of the 27 boards returns exactly 99%, symmetric, with edges up to 1,000x, and every drop can be checked against its seeds.
- Round structure
- Single decision. Choose rows, risk and stake; one drop settles.
- Session fit
- Quick sessions. Single player. Good to watch: the drop is the show.
- Stakes in this build
- 0.10 to 100 demo credits. 0.10 to 100.00 per drop.

Bucket k of n rows is reached with chance C(n, k) / 2n. All 27 tables are fixed constants, symmetric and exact: the chances times the multipliers come to exactly 99.00% for every one. An exact 98% set is also built. The top payout is 1,000× the stake (16 rows, high risk).
Pace
1.8 s a round, about 2,000 rounds an hour. Measured in Chrome with every control pressed as soon as it was enabled, so this is a ceiling with no thinking time.
GGR / 1,000 rounds is the theoretical gross gaming revenue from 1,000 rounds at a total stake of 1.00: house edge × 1,000. Volatility is the standard deviation of one round’s total return per 1.00 of total stake. Low under 1.5, Medium 1.5 to under 5, High 5 to under 15, Very high 15 and over. For scale: an even-money roulette bet is 1.00, a straight-up number 5.84.
