Finnegan is a leprechaun who likes to invent and try out different potions, resulting in the Finnegan’s Formula slot! This exciting game from Kalamba Games looks fantastic and has an Irish and leprechaun theme. In the background, you can see Finnegan’s workstation, and a fantasy tune plays as you play! The different symbols also follow this theme, and there are also symbols depicting Finnegan himself. We also love the unique features of this game. There is the K-CASH feature that allows you to build up a large bonus prize pool, and changes the height of the reels! If this sounds exciting, you can play Finnegan’s Formula for free at GoodLuckMate.

How to play

Finnegan’s Formula is a non-standard video slot with a variable ways-to-win figure of 1024-7776. This changes depending on how many rows are active. In total, there are 5 reels, and a maximum of 6 rows. However, the number of rows for each reel in-play can change. They can change independently of each other too.

You can easily select your bet value by clicking the coin icon. There is a decent bet range and the minimum/maximum values are €0.50 and €50.00. Therefore, anyone should be able to have fun, with bet values they are comfortable spending.

This exciting video slot also has both a turbo spin and an autoplay option. The autoplay only has basic functionality - simply click the autoplay button and it will spin until you stop it, or your account balance is 0.

Symbols and payouts

The Finnegan’s Formula slot has a variety of basic and bonus symbols. This makes for a fun and entertaining game. The base symbols are split into low and high-tier. All payouts listed are based on the total bet.

The low-tier icons represent different playing cards. They are the 9, 10, jack, queen, king, and ace. The 9 actually pays if you get 2 symbols at 0.06x, whereas the others only payout for 3 or more. The 10, jack, and queen all have a 1.5x multiplier for 5 symbols. Next, the king and ace give a 1.8x multiplier for 5 symbols.

The higher-tier symbols are different Irish icons - a pipe, a tankard, Finnegan’s hat, a lucky horseshoe, and a clover. The pipe and tankard pay 2.5x for 5 symbols, whilst the hat and horseshoe pay 3x. Finally, the clover is the top-paying base symbol at 5x for 5 symbols. 

There is also a wild symbol and a bonus symbol. The wild symbol is Finnegan and can appear on any reel. It also substitutes for all other icons except the bonus symbol. The bonus symbol triggers the free spins, and it also has a maximum payout of 10x for 5 symbols. More info about the bonus icon is detailed below.

Best Finnegan’s Formula bonus feature

The best Finnegan’s Formula bonus feature is the free spins. However, we must discuss the K-CASH feature first. At the top of each reel, there is a value. This is the K-CASH value. During spins, you can get K-CASH symbols that have a value. This value is added to the value at the top of the reels.

If a K-CASH reset symbol appears, the height of the reel is reset to 4, and the player is awarded the cash value that is built up in the total at the top of the reel! The K-CASH symbol is also responsible for randomly determining if the row height increases or not.

Now onto the Finnegan’s Formula free spins! You are awarded 3 initial free spins if you get 3 or more bonus symbols. If you get K-CASH symbols during the bonus spins, this resets the current number of remaining bonus spins to 3!

Also, at the end of the free spins, you are automatically awarded any built-up K-CASH bonus! The game also has a Hyper Bonus feature where you can buy the free spins instantly.

RTP & volatility

Finnegan’s Formula is a highly volatile slot. This means that whilst you won’t win often, you will have a greater chance of jackpot prizes. Also, Finnegan’s Formula RTP is an impressive 97.03%. This is really high as the average for video slots is 94-96%.
