## What is ShikiRoji?

A logic puzzle with no numbers — just color.

Fill every bold-outlined block with the right colors, one of each. The same color can never touch itself, not even diagonally — and that is the whole rulebook. Start from the given cells, build up small deductions like "only blue can go here," and every single puzzle falls to pure reasoning. No guessing, ever.

NO PENALTIES, NO PRESSURE
There are no lives, no tickets, no countdown timers, and no penalty for mistakes. Undo is unlimited. Play at your own pace, for as long or as little as you like.

ADS THAT STAY OUT OF YOUR WAY
ShikiRoji is free to play and supported by ads, but you will never see an ad on the board while you are solving. Full-screen ads appear only once every few stages, with time in between, and never right at launch. Rewarded videos (for extra hints) are always your choice.

WHAT'S INSIDE
- 200 puzzles, every one solvable by logic alone (5 difficulty levels, from beginner to expert)
- A new Daily Puzzle every day
- Stuck? Hints that explain the reasoning behind the next move (3 free every day)
- Achievements, play statistics, and full dark mode support
- Symbol Mode adds a distinct shape to every color, supporting color-vision accessibility
- Works completely offline, with a small and lightweight download

Five minutes on your commute, ten minutes before bed. Enjoy the quiet satisfaction of a puzzle solved by pure thought.
