Free Spins Bonus

What is an online slot game without a few free spins? The Nitropolis 4 slot game is renowned for its fascinating bonus features.

During free spins, big nitro reels remain stagnant until the end of the free spin round. Each recorded win enhances the safety level by one row.

Subsequent free spins fill the grid to the current safety level. This can trigger a maximum of 8 rows. If one of the triggering symbols is a Super Bonus symbol, then the Super Bonus Game is awarded. In this round, max rows and both ways are always active.
