Wild Blood by Play'n GO is a five-reel video slot with a horror and Halloween theme, released in 2013. The game uses 15 paylines and low-to-medium volatility, with stakes ranging from 0.01 to 75. Players looking for the demo version can play for free to study the layout and practice before playing for real money.
The slot features a wild symbol that substitutes for most other symbols, while a wild on reel 3 expands to cover the full reel. Bonus play includes four separate rounds, among them a re-spin feature triggered by an expanded wild on reel 1 and medallions on reels 2 and 4, plus a free spins sequence where reel 3 stays covered by a stationary expanded wild. During free spins, additional medallions can award extra spins, with the feature extending up to 50 free spins.
Three bonus scatter symbols activate the Pick-the-Blood game, where players choose blood vials until the feature ends. After that, a prize-multiplier free spins round begins, starting at 2 and rising to 5 when two or more Wild Blood scatter symbols appear. The optional Gamble round allows a win to be doubled by guessing colour or quadrupled by guessing suit, with up to five consecutive attempts and a limit of 2,500 coins.
