Under the Rainbow Slot Review

Under the Rainbow Review 2026

In a 5-reel game with 10 paylines, Under the Rainbow extracts plenty out of its format. The leprechauns and rainbows styling runs through each symbol, animation and sound. Everything that follows was tested first-hand as of July 22, 2026.

Symbols and Theme

The symbol set features pot o' gold, accordion, green top hat, shamrock and celtic knot necklace — cohesive and clear at fast spin settings. The wild symbol here is a leprechaun, substituting for other symbols to finish wins. Hit multiple rainbow scatters and the session turns interesting quickly. The wild-and-scatter combo hands Under the Rainbow two engines toward surprise payouts.

Feature Play

Land three rainbow scatter symbols awards 10 free games and the Free Games kicks in — easily the slot's best stretch. Bonus pacing felt reasonable during our review sessions — neither starved nor flooded.

Stake Options and Top Payouts

From 0.01 and 20 per spin, Under the Rainbow spans a full betting spectrum. With 10 lines in play, dead spells remain tolerable. Set your loss limit ahead of spinning; Under the Rainbow is fun that way.

Rooms Carrying Under the Rainbow

Most rooms carrying Merkur should stock it — try at Rooli. As a change of pace, alternate with Ship of Dreams and Sonnenkafer — similar DNA, different skins.

Final Verdict on Under the Rainbow

Bottom line: one of the more complete Merkur releases our team has tested recently. If the leprechauns and rainbows vibe speaks to you, Under the Rainbow becomes a natural pick. Short sessions, set budgets, no chasing — it's how Under the Rainbow remains entertainment.
