Multipliers mark specific grid locations to escalate the winning potential of subsequent drops. According to Pragmatic Play's official game rules, once a cluster explodes twice in the exact same spot, a 2x multiplier appears. This value doubles with consecutive hits in that area, progressing through 4x, 8x, 16x, 32x, 64x and capping at 128x.
When multiple multiplier spots are part of the same winning cluster, their values are added together (not multiplied). For example, if a cluster covers one 8x spot and one 4x spot, the total multiplier applied to that cluster payout is 12x.
Critical distinction: in the base game, all multiplier spots reset after the tumble sequence ends and a new spin begins. In Free Spins, multiplier spots persist and accumulate throughout the entire bonus round. This is the single most important mechanical difference and the primary reason the bonus round generates larger payouts.
Here is a real scenario worth noting. One user was confused by the low base game payouts despite frequent tumbles. She decided to monitor how multiplier cells reset between standard spins. She learned that multipliers only persist during the bonus round. Consequently, she strictly limited her base game budget, understanding that the high maximum win framing acts merely as a theoretical cap.
Behavioural research on near-miss outcomes in online slots found that outcomes close to a win produced significantly higher motivation and persistence compared to ordinary losses, despite identical monetary results. Keep this in mind when grid spots show multipliers climbing but the cluster just misses connecting. The psychological pull to continue is by design, not evidence that a big win is imminent.
