Plinko multipliers — where the numbers come from

The relationship

A slot appearing once in a thousand drops can carry a huge multiplier without costing the operator anything, because it almost never pays. A slot appearing half the time must carry a small one. The payout table is the odds turned upside down and scaled to hit the target RTP.

Typical shapes

Setting	Centre	Edge	Feel
8 rows, low	0.5×	5.6×	gentle, frequent small returns
12 rows, medium	0.3×	33×	mixed
16 rows, high	0.2×	1000×	long droughts, rare spikes

Exact values differ between studios; the pattern does not.

A quick sanity check. Multiply each multiplier by its probability from the odds table and add them up. The total should land near the published RTP. If a site advertises a table where the sum exceeds one, either the table is wrong or the probabilities are not what you assume.
