About Rock 'n' Lock
The main feature is a respin round. Special symbols that land during it stay locked in place, each new one resets the respin counter, and the round ends when the respins run out or the grid fills.
Open the paytable before you play to see symbol values and feature rules. Results are random, and the RTP shown in the info panel is a long-term average across millions of spins, not a prediction for a single session.
