Nine lines on five reels

Nine paylines is a small number, so the layout is simple to follow and a stake is spread over few lines. Check the paytable in the game for symbol values.

Thunderkick has several siblings in the Beat the Beast set: Cerberus' Inferno, Kraken's Lair and Quetzalcoatl's Trial. If you like one, the others are easy to compare.

Interpreting 96.14%

Of every 100 staked, a game at this level is built to return 96.14 across a vast number of spins and keep 3.86. That is the house edge, and it cannot tell you whether one particular session will win or lose. Our RTP explained page has the background.

Volatility is not stated, so see slot volatility to understand what that means for risk. Operators can pick a different RTP configuration, so the rules screen is worth a glance.
