About this game

Prism Mosaic is an original PokiiiGame relaxing puzzle inspired by gem-sort coloring games. Each level is a jewel picture. Gems come one at a time from a shuffled bag. Only the open edge of the mosaic (glowing tiles) can be filled — placing gems unlocks tiles further inside.

That is why the holding shelf matters: if the current gem’s color is not open yet, park it on one of four shelf slots. Tap a parked gem later when its tiles unlock. Fill the shelf with no legal moves and the level jams, so planning which colors to hold is the real puzzle.

Eight handcrafted pictures — Ruby Heart, Golden Star, Ocean Wave, Candy Flower, Lucky Fish, Moon Cat, Ice Castle, and Sunset Tree — keep short sessions fresh. Diamond-shaped gems, ghost previews, and a soft neon UI are built for phones and desktop.

Who this is for: players who enjoy gem sorting and pixel mosaic reveals. Who should skip it: fans of timed runners or multiplayer lobbies.

Prism Mosaic ships as a local HTML5 game in the PokiiiGame theme — original branding and levels, not a clone of any store app.

How To Play

  • Tap Play to start the current picture.
  • You always have one current gem from the bag.
  • Tap a glowing open tile that matches its color to place it.
  • If that color is not open yet, tap Park on shelf (or an empty shelf slot).
  • Tap a parked gem to bring it back (or swap with the current gem).
  • Fill every tile to reveal the artwork. Use Hint if you are stuck.

Tips & Tricks

  • Short calm clears beat rushing every sparkle.
