Overview

COSMIC HOLES Junior is a casual puzzle and strategy game from solo developer and publisher Fabien Corblin, released on November 10, 2026. It takes the core idea of the original COSMIC HOLES and reshapes it into a gentler, more approachable experience set against a calm space backdrop. The tagline says it plainly: aliens don't play Sudoku—they play COSMIC HOLES.

Highlights

  • 300 logic problems that ramp up gradually, with a smoother difficulty curve than the original game.
  • Dynamic laws built around the five elements of Chinese cosmology, governed by four logical rules you must follow.
  • Extra in-game aids, no sentinel enemies, and a thousand stars to collect for surprises along the way.

The puzzle design leans on deduction rather than reflexes. Each board follows the shifting relationships between the five elements, and your job is to read those rules and work out a valid arrangement.

Because the Junior version removes the sentinel enemies that punished fast play in the original, the pace stays unhurried—you can sit with a board, test an idea, and back out without pressure. Additional aids are there for anyone who gets stuck, which fits the relaxed atmosphere the store page promises.

Who It's For

This one suits players who enjoy logic puzzles and deduction games but want a softer on-ramp than a punishing brain-teaser. The space theme and atmospheric presentation should appeal to anyone who likes to wind down with a quiet strategy session. Full controller support and a keyboard-only option mean you can play comfortably however you prefer to sit. With interface support for a very wide range of languages, including Japanese, it is easy to recommend to international puzzle fans.
