How to Play Agent 51

Agent 51 is played on a 5-reel, 3-row layout with 20 fixed paylines. Winning combinations are formed by matching symbols across active paylines from left to right.

Polaroid symbols can also apply increasing multipliers to winning combinations, adding further payout potential.
