Gamdom Plinko: how it works, rows, risk and odds

Gamdom Plinko is a drop game in the Gamdom Originals range. A ball falls from the
top of a triangle of pegs, bounces left or right at each row, and lands in one of the multiplier slots
along the bottom. The slot decides your payout. Slots near the middle pay below or around your stake;
slots at the far edges pay the big multipliers.

Gamdom's own description is "drop the ball and watch it bounce toward a multiplier". There is no timing
and nothing to do once the ball is dropped. The decisions come before: how much to bet, how many rows,
and how much risk. Gamdom lists Plinko among the Originals at around 99% RTP, and publishes sample code
to check each drop.

1. Set your stake. Originals start from about $0.01; Plinko's maximum bet is shown in the game.
2. Choose the number of rows. More rows mean more slots and wider extremes. Reviews of Gamdom's

version describe a range of 8 to 16 rows.

1. Choose the risk level. Higher risk pushes value toward the edge slots and lowers the middle.
2. Drop the ball. The path and the landing slot come from the game hash.
3. Get paid the slot's multiplier times your stake.

Gamdom's help article also mentions multi-ball drops and other options such as choosing where the ball
starts. Features change over time, so use what the current game panel shows. Whatever the options, the
payout table on screen already includes the edge.

At each row the ball goes left or right with equal chance, so the landing slot follows a binomial
distribution. With n rows there are n + 1 slots, and the chance of the far-left (or far-right) slot is
1 in 2ⁿ.

The slot next to the edge is far more common: at 16 rows it is about 0.024%, and two in from the edge
about 0.18%. Most drops land in the middle third, which is why middle multipliers sit below 1x on higher
risk settings: that is where the game recovers the value it pays out at the edges.

These figures come from the binomial maths, not from Gamdom's paytable. The multipliers on screen are
set so that, averaged across all slots, the return is about 99%. Rows and risk change the shape of that
return, never the average.

Auto mode drops ball after ball at your chosen stake, with options for the number of drops, stake changes
after wins or losses, and stop-on-profit and stop-on-loss limits.

Plinko drops are quick and visually satisfying, which makes long auto runs easy to start and hard to
judge. Set a finite number of drops and a stop-on-loss, and look at total wagered as well as your
balance. The Plinko strategy guide covers settings that keep sessions under
control.

Low risk, many rows

Lots of slots near 1x make results feel steady, but the edge is the same. Small losses add up over many
drops.

High risk, waiting for an edge slot

At 16 rows the far edges are about 1 in 65,536 each. A long run without one does not make the next drop
more likely to reach it.

Changing settings after a loss

Switching to high risk to "win it back" increases the swing, not the expected return.

Reading the animation

The bouncing ball is a picture of a path already set by the game hash. There is no physics to predict.

Gamdom's Originals use a chain of ten million SHA-256 hashes generated from a secret seed, published by
the final hash and played in reverse. Each finished game's hash is published, and hashing it once must
match the previous game's hash.

For Plinko, Gamdom links sample code that turns a game hash into the ball's left-right path and the
final slot for your rows and risk. Paste the hash from your bet details and compare the slot with your
result. The Gamdom provably fair guide explains each step.

• Pick rows and risk once per session. Constant changes are chasing in disguise.
• Budget for dry spells on high risk: most drops return less than the stake.
• Keep stakes small relative to the session budget. Plinko is a volume game.
• Count rewards as a rebate. Gamdom rakeback gives part of the edge back; it

does not make Plinko profitable.

For a break, Gamdom offers self-exclusion for 1, 5 or 8 days, and longer closures through support. The
