Rainbow Reels

Rainbow Reels is an Irish-themed slot from Pragmatic Play with a grid of fixed lines and an unusual layered system: every position holds a stack of symbol layers. When a symbol takes part in a win, it is removed and the next layer beneath is revealed, which might be a higher or lower symbol or a wild.

Scatters start the free spins and pay a prize on arrival. During the round, peeling works the same way, but when a position reaches its deepest layer, a wild appears and stays for several uses before it disappears. Late in a bonus, deep positions can therefore produce wilds that last through multiple spins.

It may suit players who like a mechanic with memory, where each position slowly changes. The free demo uses play credits, no real money is involved, and results are random. The published RTP is 96.07%.
