Prime Zone is a five reel slot with three rows and ten fixed paylines; pastel colours and a 1980s soundtrack create a Miami Vice-like atmosphere on what could be a Florida beachfront behind those reels.

The four high value symbols include red sevens, blue sevens, sparkling diamonds and golden bells;playing card symbols in red, green, purple and blue represent the lower values.

The wild is the golden ‘Wild’ which appears on all reels and will substitute for all other standard symbols to help form winning combos – each extra wild in a payline will add 1x to the multiplier for that win. The red and gold bonus symbol is the key to the main feature.
