Chimp Recall
Read full descriptionHide full description
Numbers flash on a grid. Tap the first one and the rest go blank — now tap them all back, in order. This is the famous working-memory task in which chimpanzees embarrass humans. The lab chimps handle nine items. See where you stall. FOUR WAYS TO PLAY • Classic — start at four numbers, +1 every clear, three strikes and you're out. • Levels — a 60-level ladder with three-star ratings. Early rungs are a warm welcome; from level 21 the numbers hide on a timer, and from 41 the tiles SLIDE to new positions after masking. Level 60 is genuinely elite. • Daily — eight boards, identical worldwide, one attempt per day. • Reverse & Zen — tap descending, or practice without strikes (Pro). EARN AS YOU CLIMB • Nine goals with live progress — including the Chimp Benchmark: hold nine numbers, the same as a lab chimpanzee. • Six badges, one every ten levels — from First Ten to Chimp Class. • Clear level 20 to recolour the whole game. • Clear level 30 to put your own photo on the tiles. MADE WITH ACTUAL CARE • Big, thumb-friendly tiles. Instant input, satisfying haptics. • Global leaderboards via Game Center: best board, highest level, daily. • Plays offline. No accounts, ever. • Occasional ads between runs — Chimp Recall Pro removes them for good. CHIMP RECALL PRO Removes ads and unlocks Zen and Reverse modes, every level, and the alternate app icons.

Verdict
The clearest difference is in-app purchases: Chimp Recall at none against ZigZag's 2. Chimp Recall also leads on update cadence (fortnightly vs every 2 months). ZigZag's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price and ads there is nothing between them.
