Fold Trace

FoldTrace is a paper-folding puzzle for people who like to think in space—not swipe through noise. A sheet is folded, punched through the stacked layers, and frozen in place. Your job: tap every cell on the original grid where a hole will appear once the paper is fully unfolded. Submit, watch the stack open in 3D, and see exactly what you got right. The idea comes from the classic Paper Folding Test used in cognitive research since 1976—here as a calm, premium-feeling game. No hype about “brain scores.” Just a famously studied spatial task, polished for your phone. CONTENT THAT GOES DEEP • Easy — 50 curated 4×4 puzzles, one fold. A gentle on-ramp. • Medium — 1,824 puzzles, two folds. The heart of the journey. • Hard — 52,464 puzzles, three folds. Territory for players who want to stay a while. In all, more than 54,000 hand-curated, deterministic levels—no random filler. A DAILY RITUAL Every local midnight, the same four puzzles appear for everyone: one easy, two medium, one hard. Clear all four at three stars to earn a +200 perfect-daily bonus toward the global leaderboard. Miss a day? Tomorrow is a fresh sheet.
