THE FAMILY BUSINESS

Five reels, four rows, 25 fixed lines. Lines pay left to right from reel one. Only the highest win on each line counts.

WALKING CONTRACTS

A Wild Contract lands on reels 2 to 5, sticks, and the reels respin. Every respin the contract walks one reel to the left and keeps paying, until it walks off reel one. Fresh contracts landing during a walk join the chain.

DEAL WITH THE DEVIL

Three or more Blood Pacts award 10 free spins and the cabinet is signed over. Every contract now carries a multiplier that upgrades each time it walks: ×2 → ×3 → ×5 → ×10 → ×25. Two contracts on the same line multiply together.

BUY FEATURE

Buy FS enters the deal immediately for 127.5× your bet. That price is set from the measured value of the feature, so the purchase returns the same 96% as the base game.

PAYTABLE (× bet, per line)
