Push. Slide. Solve. No forced ads. No paywall. No timer. Every level included for free. Just you and the puzzle. Guide a small robot across handcrafted ice grids in a sliding puzzle where every push matters. Push colored crystal blocks and watch them glide until they hit a wall, another block, or a special obstacle. Match every block to its target in as few moves as possible. Start with simple slides. Then discover pushers that redirect blocks, obstacles you can crush, wildcards that match any target, and blocks that copy their neighbors. Every level is a handcrafted puzzle with its own twist. GENUINELY FREE All 60+ levels are completely free. Undo is unlimited. Skip, colorblind mode, and original music are all included. If you want a hint on a tricky level, you can earn gems by watching a short video — or grab a gem pack if you'd rather skip the ads entirely. PLAY YOUR WAY • No timer — think as long as you need • Unlimited undo — experiment freely and refine your solution • Hints when you're stuck — see which block to push next • Skip tricky levels — come back later • Colorblind mode — patterns distinguish block types 60+ LEVELS Handcrafted puzzles across three difficulty tiers — from gentle introductions to mind-bending challenges.

Verdict

The call

The clearest difference is rating: Ice Bot at 4.8 against NineGaps's 4.0. Ice Bot also leads on update cadence (every 5 days vs every 26 months). NineGaps's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, review sentiment, ratings volume and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Ice Bot holds the better App Store score, 4.8 against 4.0. Both are backed by a comparable volume of ratings — 10 and 24 respectively. Written reviews complicate that: 88% of NineGaps's written reviews are positive against 83% of Ice Bot's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NineGaps ships an update every 26 months, Ice Bot every 5 days. The most recent releases landed on October 31, 2026 and November 8, 2026 respectively.
