An ice sliding puzzle drawn as a technical chart on bone paper. A black chevron slides over blue cells until a black rock or the edge stops it. A hatched snowdrift halts it on the spot, an orange target is the exit, and orange crosses are flakes to gather. 1.0 Rules 1.1 Swipe to slide. The chevron always travels as far as it can. 1.2 Each level has a par from a solver. Clear it for one star, take all flakes for two, and both within par for three. 1.3 A table above the board reads moves, par, flakes and moves still to go. 2.0 Level path 2.1 Thirty levels on a zigzag path in five sections: Shore Ice, Drift Field, Pressure Ridge and two more beyond. 2.2 The field grows from 7×7 to 12×12, and each level opens the one after it. 3.0 Daily board 3.1 One board per date with a day streak and 25 points for the first clear of the day. 4.0 Duel 4.1 Pass and play for players A and B on one device. 4.2 Both solve the same board in turn, with a hand-over screen between them. Fewer moves takes the round, over three rounds. 5.0 Workshop 5.1 Points come from fresh stars, daily boards and duels. 5.2 Hint packs mark the next ideal stop, Route peek shows the whole route once, and Par meter keeps a live count of the moves still needed. 6.0 Stats 6.1 A numbered table of levels, stars, perfect levels, streak, dailies, duels, moves, cells slid, hints and points, plus progress per section. 7.0 Setup 7.1 Haptics, a progress reset and the animated background: millimetre grid, an orange scan line moving down and drifting floe outlines. Switch it off here for a still screen. 7.2 The game plays offline with no account needed.
