Lucky Penny is a 6x5 slot from 3 Oaks Gaming released in August 2024. The game uses a cluster-style system where wins are awarded when at least eight matching symbols land anywhere on the reels. A cascading reels mechanic then removes winning symbols and allows new ones to fall into place, creating the possibility of several wins from one spin.
The feature set includes a Wild symbol that helps complete winning combinations, plus Penny Symbols carrying multipliers from x2 to x1,000. These multipliers can land with help from the Leprechaun or appear on their own, and multiple multipliers can combine during the same spin. The Irish theme is built around hills, rainbows and leprechaun imagery, while the base game supports bets from 0.2 to 25.
A free spins round is the main bonus feature. During free spins, each multiplier contributes to a growing total multiplier, increasing as the round continues. Players can use the demo version to play for free and practice before playing for real money, with access to the same core mechanics, multipliers and bonus games described in the full review.
