01
Connect five
Five or more matching symbols, touching by a side, pay together. A wild can sit in more than one group.
02
Take the pie
Pies pay the number on the face. A hit from a cannon or bomb pays the pie, then turns that cell wild.
03
Run the line
Pick a rat. To Win pays first. Each Way can pay first, second and third. The purse can reach 50,000×.
The crew
Six rats. One board.
The high symbols are the crew. Clusters, pies, keys and chests do the paying in the base game. Cannons, bombs and a parrot join once Free Spins open. The races leave the reels entirely.
01 / Mechanics
Clusters
Groups of five or more regular symbols pay when they touch by a side. Diagonals do not connect. A wild can belong to different symbols on the same board. Winning cells leave and the board tumbles.
02 / Mechanics
Pies
Each pie pays the value on its face, in base stakes, up to the round cap. After a cluster, adjacent pies pay and leave. A cannon, bomb or ember that hits a pie pays it at once and leaves a wild.
03 / Mechanics
Cannons
In Free Spins, a cannon paints a rectangle on the board. Pies inside pay and become wild. Scatter, keys, chests and parrots are left alone.
04 / Mechanics
Wild bombs
A wild bomb clears a local rectangle in Free Spins, then may throw embers onto other cells. Hit pies pay and become wild.
05 / Mechanics
Parrot
A parrot collects every pie in view. The pies and the parrot then leave the board.
06 / Mechanics
Chests and keys
A key touching a chest by a side unlocks it. Chests pay 25×, 100×, 250× or 1,000×. Unused keys stay.
07 / Mechanics
Free Spins
Three or more Scatters award that count plus five Free Spins, including during tumbles. A rare Treasure Raid can replace the first free spin with a chest-heavy board. It does not add a spin, and it is not a guaranteed max win.
Play modes
Pick the pressure.
Seven ways onto the same board. Cost is a multiple of total bet. The published RTP arrives with the title.
