Plinko simulator: 1,000 free drops on the real payout tables

How to use it

1. Choose the version, then the rows and risk. The board and the payout labels update straight away.
2. Press Drop one ball to watch a single ball fall, or Drop 1,000 balls to fill the chart in one go.
3. Read the four numbers above the chart: how many balls you’ve dropped, what $1 a drop would have returned on average, the biggest multiplier you’ve hit, and the RTP of the table you picked.
4. Press Clear to start again. Changing the rows or risk also clears the count, so every result belongs to one table.

What the chart shows

Each gold bar is one pocket, from the left edge to the right. Its height is how many balls landed there. The dashed white line on each bar is where the exact odds say it should be for the number of balls you’ve dropped. Hover or tap a bar for the exact count and chance, or open See the numbers for each pocket under the chart for the full table.

After 1,000 drops on 8 rows you’ll usually see the middle pocket close to 273 balls, its share of 27.34%, while the two edges get about four balls each. On 16 rows the edges are so rare (one in 65,536 each) that most 1,000-ball runs never reach them.

Why a short run drifts from the RTP

The “back per $1” figure moves around a lot at first. On High risk, a single edge hit can lift a session above $1 back per $1 staked, and a long run of 0.2× pockets can drag it well below. I ran seven sessions of 1,000 drops on BGaming’s tables: they returned anywhere from $952.20 to $1,086.40 for $1,000 staked. The full list is on the strategy page.

The table’s RTP is where that figure heads as the drops pile up. BGaming’s tables sit between 98.91% and 99.16% ², and the simulator works each one out from the exact odds, so you can see the target next to your result.

What’s loaded

All nine row counts (8 to 16) and all three risk levels of BGaming Plinko, exactly as the free demo returns them ¹. Other versions are added once their tables are confirmed on the provider’s own pages; see the version comparison for what each provider publishes.

How it works

Every ball is a string of random left-or-right choices, one per row, each with a 50% chance. The random numbers come from your browser’s crypto.getRandomValues(), the generator built for security work ³. The pocket is simply the number of right turns, which is why the middle pockets fill first: there are many more paths to the centre than to the edges.

This is a model of the maths. Real games decide each drop from a server seed, a client seed and a round number, which is what makes them checkable afterwards; our provably fair guide explains how. The simulator isn’t connected to any casino, and nothing you do here can tell you where a real ball will land.
