Jewel Box is a 5-reel video slot game. You can activate up to 15 lines and bet up to 5 coins/line. Lines must be activated in numerical order (1,2,3,4, etc.).
Prizes are for combinations of adjacent symbols of a kind on selected lines. A winning combination can start from reels 1,2 or 3. Only the highest win is paid per line.
Jewel Box includes four wild symbols (the multipliers, x2, x3, x4, x5) and a bonus symbol (the Jewel Box). The wild symbol substitutes for any other reel symbol (except for the bonus symbol) to help comprise winning combinations. A winning combination that includes a wild symbol pays x2, x3, x4 or x5 the normal prize.
Three bonus symbols anywhere on the reels triggers the Pick-a-Prize bonus where you select one of the bonus symbols to reveal the prize won.
You can attempt to multiply your prize in the optional Gamble round. Press the GAMBLE button after winning a prize to start the round. Your objective is to correctly guess the colour or suit of a face-down card. Take your guess by clicking the appropriate button. If you correctly predict the colour, you double your prize. If you correctly predict the suit, you quadruple your prize. You can play the Gamble round up to five times in succession and up to a limit of 2500 coins.
The wild symbols only appear on reel 3. The Jewel Box is a scatter symbol and only appears on reels 1,3 and 5.
