Meet Tile Shift. A familiar puzzle with room to think.
Play Tile Shift ↗Learn Shade Link, one idea at a time.
Start with the rules, try the same board, then work toward an independent challenge. Each lesson has its own worked example.
- 1Beginner rules ↗
Learn three shading rules on a fixed four-by-four board, reproduce a complete answer, and test why side contact and an isolated unshaded corner fail.
- 2Solving strategy ↗
Use a different fixed board to force a third copy out, reject choices that isolate kept cells, and compare five checked deductions with reproducible wrong branches.
- 3Practice challenge ↗
Try a new fixed board, fill a three-count prediction ledger, and test an extra shade that splits a valid path into three groups. Reveal the full deductions and recovery steps after trying.

Shade Link practice: predict the counts and protect the connector.
Try a new fixed board, fill a three-count prediction ledger, and test an extra shade that splits a valid path into three groups. Reveal the full deductions and recovery steps after trying.
Lesson 2Solving strategyShade Link strategy: use adjacent pairs, then protect the kept paths.
Use a different fixed board to force a third copy out, reject choices that isolate kept cells, and compare five checked deductions with reproducible wrong branches.
Lesson 1Beginner rulesShade Link for beginners: remove repeats and keep a connected path.
Learn three shading rules on a fixed four-by-four board, reproduce a complete answer, and test why side contact and an isolated unshaded corner fail.
Take your time.
That’s part of the fun.
Our puzzles have no countdowns, entry fees, or public leaderboards. Try a move, notice what changes, and make the next one a little more deliberate. The guides explain the rules and the reasoning, with examples you can try for yourself.
