About the game

3 Lucky Rainbows Action Boost SpinUP is SpinPlay Games' October 2025 upgrade to their 2023 Irish luck slot, exclusively distributed by Games Global. The 5×4 grid carries 20 fixed paylines — expanding to 6 rows and 40 paylines when the Green Coin free spin mode is active.

The Action Boost SpinUP system offers three distinct free spin modes, each triggered by collecting differently-coloured coin symbols during base play. Green Coin Free Spins expand the reel set to 6 rows with nudging Wilds and symbol upgrades. Red Coin Free Spins feature Clover/Shamrock collection toward fixed jackpot tiers from Mini to Mega. Purple Coin Free Spins launch with escalating multipliers beginning at 2×. Collecting multiple coin types simultaneously unlocks the Multi-Coin hybrid — running all three modes at once.

Max win is 5,000× (€250,000 at maximum bet). RTP is 96.49% on the SpinUP variant, up from 96.27% on the original Action Boost release.
