How Boosters Affect RTP
A Lightning Round scales the payout multiplier, so its contribution to RTP is multiplicative on the base figure, not a flat percentage-point addition. It also differs per selection, not merely per game: each tier boosts only the options inside its own eligible pool, so an option outside that pool gains nothing from that tier, and a bet covering more of a pool (forecast, tricast) gains proportionally more than a single-selection bet. Some games have no Lightning Rounds configured at all — Coin Flip and Footfall — so their effective RTP equals their base RTP.
Published Effective RTP figures are quoted at player level 0 and cover Lightning Rounds only. Streak Multipliers, Player Levels and Daily Check-in add further on top where a game offers them.
Per-selection figures and the full derivation are in Game Rules §4.
