About

Trace

Features
Read full description

Trace is a minimalist brain puzzle game about memory and steady hands. Each level briefly reveals a maze โ€” walls or a glowing path โ€” and then it's gone. Now retrace the route from start to finish in one continuous gesture. From memory. No timer on the solve phase. You don't have to be fast. You have to remember, and trust what you remember. BRAIN TRAINING Trace works as a daily exercise for short-term memory, spatial reasoning, and focused attention. A few seconds to absorb the maze, then it's just you and the trace you draw from memory. Short sessions, real cognitive load โ€” five to ten minutes a day adds up. CORE MECHANIC โ€ข Memorize the maze in 3โ€“8 seconds โ€ข Draw the solution in one unbroken motion โ€ข Fail, retry โ€” but tougher levels don't fully reset CHECKPOINT FLAGS Before each attempt you can plant a flag mid-path. If your stroke reaches the flag but fails later, that section banks โ€” next try starts already-completed up to the flag. The game rewards careful play, not frantic retries. FOUR CHAPTERS โ€ข Spark โ€” tutorial, simple paths โ€ข Echo โ€” 3ร—3 and 4ร—4 walls โ€ข Dusk โ€” start and finish hidden during memorization โ€ข Abyss โ€” 5ร—5+ grids, sometimes rotated between memorize and draw WHAT IT TRAINS โ€ข Short-term memory โ€” hold the path in mind after a brief reveal โ€ข Spatial reasoning โ€” a route, not a picture โ€ข Concentration โ€” one steady gesture demands certainty โ€ข Attention to detail โ€” every cell matters LOOK Clean geometry, calm palette, nothing extra on screen. Dark and light themes โ€” switch manually or follow system. WHO IT'S FOR For people who like puzzles calibrated to demand attention, not reflexes. Calm focus, not speed. Made for the 5โ€“15 minutes between things โ€” and effective as a regular memory workout. svyatoslavdp@gmail.com
