About

Cosmic Path

Features
Read full description

Cosmic Path is a visual memory game for brain training in deep space. Watch a comet trace a path across the grid, then draw it back from memory. HOW IT PLAYS A glowing comet flies across the board, tile by tile. Remember its route, then trace the same path with one finger. Nail it and the trail lights up. Miss a tile and you go again. It starts easy and grows with you. Paths get longer, the grid gets bigger, and new rules join one at a time: a decoy comet to ignore, paths you trace backwards, lights out while you draw, and portals that make the path jump across the board. Every few levels a boss mixes the rules into one long path. Short rounds, real focus. Squeeze in a few minutes of memory training on the bus, or chase a long run in the evening. A pattern memory game for seniors and anyone who likes a real challenge. Need a calmer pace? Relax mode lets you build your own puzzle. FEATURES - Campaign in three acts: learn each rule, combine them, then master them all. - Short lessons with a free try whenever a new rule appears. - Boss levels: one long path with combined rules. Win to earn 10 stars. - Portals: the comet dives into one portal and comes out of another. Remember every segment. - Stars on the path: collect them and spend them on skill refills, or on an arrow hint when you're stuck. - 4 skills: Slow Time, Trail, Hint and Checkpoint. Slow Time, Trail and Checkpoint last 3 rounds. - Daily Challenge: 5 rounds with a new twist for every day of the week. Keep your streak alive. - Relax mode (unlocks at level 15): choose the grid, path length, speed and rules. No pressure. - Combo multiplier for clean rounds and a session summary when you return to the menu. - Game Center: 3 leaderboards and 10 achievements. Cloud save via iCloud. - Reduce motion, haptics, and a decoy marker that doesn't rely on color. - No internet needed to play. - Optional one-time purchase removes banner and interstitial ads. - English, Polish, German, French, Spanish, Portuguese and Italian. Watch. Remember. Trace. How far can your memory take you?

Verdict

The call

The clearest difference is ads: Kakuro at none against Cosmic Path's shown. Kakuro also leads on iOS requirement (15.6 vs 17.0). Cosmic Path's advantage is update cadence (every 2 weeks vs every 4 months). On price, in-app purchases and device support there is nothing between them.
