- Book of Ming is a 5-reel, 3-row video slot with 10 paylines. The objective is to land as many identical symbols as possible along a payline. Winning combinations start on the first reel on the left (excluding SCATTER symbols) and run along an active payline to the last reel on the right. Only the highest winning combination is paid per line.
- The SCATTER symbol substitutes for all other symbols on the reels. Landing three or more SCATTER symbols will trigger 10 Free Spins, with EXTRA SCATTER symbols. Wins using a combination of SCATTER symbols only are possible. SCATTER symbols can appear on all reels. Only one SCATTER can appear on each reel.
- Landing three or more SCATTER symbols will trigger 10 Free Spins, with EXTRA SCATTER symbols. Before the start of each free spin, one of the line symbols (except for the SCATTER symbol) randomly becomes the EXTRA SCATTER symbol. EXTRA SCATTER symbols can form SCATTER wins only and cannot form part of regular line wins. If Free Spins are re-triggered, the player unlocks 10 extra Free Spins, which are added to the current number of Free Spins. Free Spins are played using the same trigger bet and paylines that were active during the normal gameplay mode in which Free Spins were triggered. During Free Spins an alternate set of reels is used.
- The RTP is 96.33%.
