Lion spins + Panther spins
Throughout the game, whenever a lion or panther symbol appears on the reels, they will be added to corresponding counters on either side of the game grid. Every 12 spins, the game switches to the daytime for lion mode and after dark for the panther. On the 12th spin, your symbols that have accumulated in the counters will be unleashed on the reels, creating standard combinations, with added awards if they land on top of each other or on top of wild symbols. It works as follows:
Getting 3 or more scatters anywhere in view triggers the free spins and you immediately score 12 freebies. There are additional benefits, conditional upon how many scatters you have:
The collection of lion and panther symbols happens the same way during free spins as it does in the base game, but once the 12th free spin happens, the game ejects both sets of symbols onto the reels, possibly giving you a grid full of wilds and multipliers which could translate into you winning the game's highest possible payout.
Paid Free Spins
If you have deep pockets and a short stack of patience, the Serengeti Kings slot game gives you the chance to buy your free spins, rather than wait for the scatters that would normally trigger them. The option gives you the effect of 3, 4 or 5 scatters for over 50x, 80x and 240x your stake, in that order. Considering the high cost of this feature, you should use your discretion before opting to use it.
It is hard to fault the overall execution of the Serengeti Kings slot. The visual and auditory design combines to create something pleasant and exciting at times. The constant presence of the lion and panther spins provides regular breaks from the monotony of spinning. The game has a decent RTP of 96.7% and volatility that veers towards high, meaning the pace is fast enough to keep your pulse slightly elevated. This is an all-round good effort from NetEnt with only the low-value payouts for standard symbols and the frankly exorbitant cost of purchasing free spins stepping in to dampen proceedings a bit. This is a title that you will find easy to come back to as there is enough here to keep you going and entertained for a while.
