Monostroke

Monostroke is a single-line drawing puzzle. Draw one continuous stroke through every required cell — no lifting your finger, no retracing your path. One simple rule. A lot of depth. ONE RULE. WORLDS OF DEPTH. Start with the basics. Then meet the mechanics, one at a time: • Walls block your path. • Ice slides you in straight lines. • Switches flip the rules mid-stroke. • Portals teleport across the board. • Veils hide what lies beneath. • Bridges let your line cross itself, cleanly. Every mechanic is taught before it's tested. THREE CHALLENGE MODES For when the basics feel too tame: • MIRROR — your stroke mirrors across an axis. • BLUEPRINT — strict, minimalist puzzles for the precise. • TALLY — hit every checkpoint as you go. Master a world to permanently unlock its visual theme. THE GAUNTLET Five floors. No retries. The line ends here. The Gauntlet is the prestige test. Earn shards from your runs and spend them on the most exclusive cosmetic in the game: the iridescent Aurora theme. META-MAPS Each region of a hand-drawn world is its own puzzle. Together, they form a complete map. Solve every sub-region of the Hourglass to complete the picture. EARN WHAT YOU WEAR Themes are unlocked through play, not paywalls. Master a world to claim its visual identity: • Paperweight — aged manuscript paper. • Tron — neon on dark glass (cyan, orange, magenta variants). • Constellation — cosmic starfields with optional aurora overlays. • Blueprint Cyanotype — drafting-paper aesthetic. • Wood — polished go-board. • Aurora · Iridescent — the prestige tier, earned with Gauntlet shards. Plus path skins, endpoint markers, and checkpoint markers — all earned in-game. THOUGHTFUL PLAY No timers on regular puzzles. No daily streaks to break. Sketch a route, retract, try again. The puzzle waits. Free to play, with optional rewarded ads. A one-time Premium purchase removes all ads and unlocks bonus coins plus a cosmetic starter pack.
