Tsumego

Tsumego — Go life-and-death puzzles — is one of the most fundamental training methods in the game of Go. By solving local life-and-death situations, players sharpen their reading ability, positional judgment, and tesuji instincts. Whether you're a beginner or an advanced amateur, doing a few tsumego problems daily is widely recognized as the most efficient way to improve your Go strength.

However, most online tsumego platforms have notable friction: some require sign-ups, others have outdated interfaces with clunky interactions, and some lack proper difficulty grading. MeTool's Tsumego was built with a clear goal: open your browser and start practicing immediately, with a beautifully rendered board, clear difficulty levels, and instant right/wrong feedback. Everything runs in your browser — no data is transmitted, no account needed, no distractions.

Beautiful board rendering: The board is drawn pixel-by-pixel on Canvas with realistic wood grain texture. Stones feature radial gradients and specular highlights, delivering visual quality far beyond typical web Go boards. Star points and grid lines are crisp and natural — the experience approaches that of a physical board.

Three difficulty tiers: Beginner (🌱) → Intermediate (⚡) → Advanced (🔥), with problems strictly grouped by difficulty. Beginner problems suit those who just learned the rules, while advanced problems test deep reading and complex tesuji — covering the full spectrum from newcomers to high-dan amateurs.

Instant feedback + hint system: After placing a stone, the result is shown immediately (green ✓ for correct / red ✗ for wrong). Hints and full answers are available on demand. Reset and retry anytime — no more guessing where you went wrong.

Progress memory: Your progress for each difficulty level is automatically saved in localStorage. Come back tomorrow and pick up right where you left off.

Pure frontend, zero privacy concerns: All logic runs locally in your browser — no uploads, no accounts. Just open the page, choose a difficulty, and start training.

If you're a Go enthusiast, spending 5–10 minutes daily on tsumego is the most effective way to improve. MeTool Tsumego provides a zero-barrier, high-quality practice environment:
