Kalamba Games takes you to a greenhouse lab where a lucky Leprechaun is preparing magical rewards for you in the slot Finnegan’s Formula. The Leprechaun has the formula for big wins, and you’re about to discover it yourself.
With a 97.03% RTP, the Ways Pays system that allows from 1,024 to 7,776 ways to win across the 5×4 grid, the Pumping mechanism and the medium to high volatility, the slot can take you to payouts of up to 6,833x the stake. To help you achieve it, you have the K-Raise mechanics, present in many slots by the developer, as well as the regular Wilds, Scatters and Free Spins.
The highest-paying 4-leaf shamrock is the symbol that pays 5x the stake for the top combo, the Leprechaun is the Wild himself which replaces all regular symbols, and the Scatter is the Pot of Gold Bonus symbol.
You can play the game for bets that start at €0.50 and go up to €60 per spin. Symbols pay anywhere on the row, as long as they land on consecutive reels. So, if ready to discover whether you have the luck of the Irish on your side, let’s begin.
Game Features
When you load the slot, you see the five pumping mechanisms above the five reels, covering 2 symbol positions each. With the K-Raise mechanics, each row at the start of the game is 4 positions high. When the pump moves, it can unblock symbol positions whenever the K-Cash bottle symbol with the rainbow brew displayed on it appears.
These symbols have a random cash prize, too, collected above the reel where they land. Since each reel can be 4 to 6 rows in height, 1,024 to 7,776 ways to win are available. When the K-Cash symbol lands without a rainbow brew, it becomes the K-Cash Reset symbol, which resets the reel to 4 rows in height and gives you its cash prize.
When you land 3 Scatters, you trigger 3 Free Spins and each cash meter resets to 2x the stake and the reels to 4 rows. K-Cash bottles expand the reels with 1 row when they land and with each expansion, the Free Spins counter resets to 3. K-Cash values continue getting collected in their respective meters. At the end of the bonus round, their values are summed and added to the total payout.
Wherever possible, you can place the HyperBonus bet and get into the Free Spins round immediately, and with this move, the RTP increases to 97.11%.

Finnegan's Formula FAQs
No, not really. You accumulate prizes on each spin, so the values do not reset, even if you change your bet level.
No. While the slot offers Wilds, there are no Multipliers available in it. You won’t see Multiplier Wilds land in the Finnegan’s Formula slot. Regular Wilds will play their usual role of a substitute.
If you play the slot for the minimum bet of €0.50, you could win up to €3,416. But, if you play it for the max bet of €60, you will scoop the top payout of €409,980! This is a pretty generous payout potential for a medium to highly volatile slot, so make sure you take a shot at it!
