How to cite

Slot Summary

Crazy Tooth Studio used 777 Rainbow Respins as its first Irish-themed release, applying its Respins concept to a Leprechaun, Clover, and Rainbow setting. Every winning spin can create another attempt over the winning positions, while Multiplier Wilds may join the respin area and raise its value. That recurring extension suits the game's High volatility and 6601x ceiling: the notable wins depend less on an isolated symbol hit than on a result that keeps adding positions and preserves multipliers into Free Spins.

How It Plays

A winning combination marks its positions for a Respin. Matching symbols landed during that attempt enlarge the active area and award another Respin.

The sequence stops when a Respin adds no new qualifying positions. This makes consecutive symbol expansion, rather than an independent base spin, the decisive event.

Theme & Atmosphere

Irish, Clover, Leprechaun, Lucky, and Rainbow themes are tied directly to the features, with the Leprechaun responsible for awarding Multiplier Wilds.

The theme changes context between ordinary play and Free Spins, but its main function is explanatory: pots signal entry, while Clovers represent multiplier values.

Features & Win Potential

Respins preserve the relevant winning area and expand it when matching symbols arrive. Random Multiplier Wilds may then be added to those active positions.

Multiplier Wilds can increase the value of connected wins, while Symbol Swap and ordinary Wild Symbol behavior support combinations outside the locking Respin sequence.

Bonus & Free Spins

Three pot Scatter Symbols trigger Free Spins. Their positions convert into Multiplier Wilds, establishing enhanced values before the first bonus result is evaluated.

During Free Spins, Multiplier Wilds become Sticky Wilds and remain fixed. Each winning combination can still activate Respins, allowing the locked multipliers to contribute repeatedly.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (94.20%), with wins capped at its top multiplier (6,601×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
