Finnegan's Formula

Finnegan’s Formula by Kalamba is a video slot with 5 reels that starts with 4 rows, set in a steampunk laboratory inhabited by a leprechaun, where traditional Irish elements blend with mechanical ingenuity. The game introduces the "K-Raise" mechanic, which allows the reels to expand up to 6 rows as special symbols called K-Cash appear. K-Cash symbols also accumulate prizes in meters above each reel, and if a related Reset symbol appears, that reel returns to 4 rows, releasing the accumulated value. The slot offers free spin modes; these are activated by landing 3 or more Scatter symbols and starts with 3 free spins, which reset to 3 each time a K-Cash symbol lands during this phase. During the free spins, the reel expansion is also maintained, helping to achieve up to 7,776 ways to win. It also features the Finnegan Wild, which can substitute for regular symbols (except scatters and K-Cash), making it easier to form winning combinations. Additionally, it includes the HyperBonus feature, which allows players to directly purchase access to the Free Spins mode, where the setup is the same as if activated by scatters. The maximum win available in this game is up to 6,833 times the bet. The game's volatility is high, meaning that while big prizes are possible, they are not very frequent.
