Dice game RTP and under/over odds
Win chance versus payout trade-offs, and operator-published edges in the originals record.

In-house dice games pay on an under or over target. You pick a roll direction and a threshold. The game draws a number on a fixed scale, often 0.00 to 100.00. The published house edge sets the long-run cost. Your target mainly changes how often you win and how large each win pays.
Win chance and payout trade-off
On a fair continuous scale from 0 to 100, an under-50 target wins about half the time before the house edge. Operators then scale the payout so the expected return matches the published edge. A tighter target pays more per win and loses more often. A wider target pays less per win and hits more often. Session results can still swing far from the long-run average.
RTP Ledger does not invent an unpublished payout curve. Read the in-game help for the exact multiplier formula on the build you play. Compare notation with RTP versus house edge.
Published operator edges
The table lists only figures traced to operator-controlled pages in the originals research record. Empty rows stay empty when a casino publishes no fetchable edge.

Provably fair limits
Some operators document HMAC or hash commitments for dice rolls. A correct recomputation can show that disclosed seeds reproduce a finished roll. It does not prove the next roll, and it does not replace the published edge. See how provably fair works and the verifier tool for supported games only.

Similar under/over math appears in Limbo target multipliers and in crash cash-out risk. Each game still needs its own published edge.
Dice RTP FAQ
What is dice game RTP?
Dice RTP is the theoretical long-run return on an under/over (or roll-over / roll-under) dice game. Several operators in the RTP Ledger originals record publish about 99% RTP (1% house edge) on named builds. Confirm the figure on the operator page for the product you use.
Does a higher win chance raise dice RTP?
On a fixed house-edge build, a higher win chance usually lowers the payout multiplier so the long-run edge stays near the published figure. Changing the target changes volatility and hit rate, not a free improvement in RTP.
Can you verify a dice round?
Some casinos publish seed inputs for in-house dice. RTP Ledger’s browser verifier recomputes supported Stake Dice rounds after the server seed is revealed. Verification does not predict the next roll.
Dice is still gambling. Published RTP is a long-run model, not a session forecast. Age rules and local law apply.
