Two sorting puzzles published by OVIVO Games, both updated through 2026. I worked on them as the Unity developer.

A calm color sorting puzzle: tap a tube to lift the top ball, drop it on a matching color, and clear the board. Hundreds of handcrafted levels go from simple warm-ups to puzzles that need real planning.

  • Hand-built level curve with hidden balls and growing tube counts
  • Smooth tap-to-move controls and satisfying ball animations
  • Every level solvable by logic, no luck involved

A cozy café sorter: drag coffee packs onto the board, group six of the same color to complete orders, and keep space free as the levels tighten up.

  • Drag-and-drop board with order goals and level progress
  • Boosters and a coin economy that support longer sessions
  • Easy to learn, with difficulty that keeps climbing
