Castle by MGA Games is a five-reel, three-row slot with 10 fixed paylines and a medieval-castle theme. The game uses cartoon-style symbols including a jester Wild, a princess scatter-linked symbol, crowns, swords, lutes, and card ranks from 10 to K. Winning combinations are formed along the fixed lines, with prizes set by the paytable.
The demo version is available for players who want to play for free and practice before playing for real money. Castle includes a free spins feature that awards 10 spins when three scatter symbols appear, with wins accumulated during the bonus round. The Wild substitutes for other symbols to help complete combinations.
After a win, a Double/Nothing feature may appear, using a roulette-style wheel that can multiply the prize or remove it. The rules screen also shows an RTP of 85%, together with help pages for the main game, free spins, and gamble mode.
