HOW TO PLAY PRIME ZONE
When it comes to visuals, they are simple, yet crisp, just like in old-school slot machines. The symbols that populate the reels are also old-school, so expect to come across plenty of Blue and Red Lucky Sevens, Diamonds, Bells, and four different card suits, which are used for low-paying symbols.
The Wild substitutes for all regular symbols and can also come with a multiplier, which can go up to 5x. The Bonus Scatter can appear only on reels 2, 3 and 4 and triggers the Prime Zone Bonus, with 7 free spins.
The rules of the game are quite simple and even mere beginners will be spinning like pros in no time at all. The 2019 release features a standard 5×3 reel grid and benefits from 10 fixed paylines, which pay left to right, starting from the leftmost reel, with three of a kind being the minimum for landing payouts.
Betting is fixed at 10 coins per spin, but you can alter the coin value and wager as low as $0.10 and as high as $100 per single spin. The command list is pretty standard and offers all the usual options.
