Wilds and the Rat King
- 259 ways: wins pay across a 5×5 grid, so there are no fixed lines to follow.
- Standard wilds: they substitute for the paying symbols and carry multipliers of up to 100x.
- Rat King wilds: they only land on reel 3, carry multipliers of up to 500x, and each holds one of four gems (red, purple, green or blue) that changes its effect.
Three free spins modes
Three, four or five Rat King scatters start 10 free spins, and the number of scatters picks the mode:
| Scatters | Mode | What changes |
|---|---|---|
| 3 | Blood Ritual | Plays like the base game, but every wild lands with at least a 2x multiplier |
| 4 | Blood Pact | A Rat King wild stays on reel 3 for the whole round and keeps adding to its multiplier |
| 5 | Blood Lust | The strongest mode: a sticky Rat King wild on reel 3 for the whole round, again keeping its multiplier gains |
Three or more scatters during any mode add 5 more free spins. Bonus buys are available where the casino offers them: 100x your bet for free spins and 500x for the Super version. Ante bets raise your stake for a better shot at the feature; with them, a spin can cost up to 1,200.
Which Rat Royale RTP will you get?
There are three settings: 96.52%, 95.50% and 94.53%. That is a two-point spread, and the casino picks which one you get. With a hit rate of about 24% (OLBG and Casinos.com both give 24.39%, or a win roughly every 4 spins) and the biggest wins coming from the wild multipliers, it is worth opening the paytable first and looking for 96.52%.
