J-POP by ELK Studios is a 6-reel, 4-row slot with large symbols, expanding rows and several wild-based features. The game uses a ways-to-win format that can increase through the bonus game, where three or more bonus symbols trigger free drops and the grid can expand to eight rows, creating up to 262,144 ways to win.
Feature symbols include Grid Flip, which turns the full grid horizontal before becoming a Wild symbol, Big Drop, which sends big symbols onto the reels and clears 1x1 payout symbols, Walking Wild, which moves to an adjacent position and raises its multiplier by x1, and Wild Box, which adds a random number of Wilds. The paytable also includes a super bonus game, with a maximum payout stated at 25,000x the bet.
A demo version is available to play for free, which allows players to review the mechanics and practice before playing for real money. ELK Studios also offers X-iter modes, ranging from lower-entry bonus access to a Super Bonus option with a guaranteed Walking Wild.
