## What is tinyLoop?

tinyLoop is a pure logic puzzle: trace a single closed loop through the grid — no
crossings, no open ends. Three rules to learn, endless depth to master. No timers,
no energy meters, no connection needed — just the quiet satisfaction of deducing
the one solution that fits.

If you love sudoku, nonogram or minesweeper, you'll feel at home here.

■ 300+ levels, a smooth difficulty curve
Start at 5×5, stretch out at 8×8, go master at 12×12. Every board is generated and
verified to have exactly one solution — always solvable by logic, never by guessing.
The first 100 levels are free.

■ Daily Challenge
A fresh puzzle every day. Build your streak and measure yourself against yesterday's you.

■ Endless library
Beyond the campaign, generate brand-new uniquely-solvable puzzles whenever you like.

■ Stuck? Three kinds of help
· Smart hints: reveal the logic pattern that cracks the next step — they teach you how
  to think, not just hand you the answer
· Hypothesis pencil: test any edge without committing, leaving no trace behind
· Undo / redo: unlimited, so you can experiment freely

■ Loop console
Draw and verify at the same time. Constraint progress and rule conflicts update live,
so you never reach the end only to discover a mistake.

■ Solve stats
Progress, solving efficiency and personal bests — your improvement, made visible.

■ Obsidian themes
A dark palette built for long thinking sessions, comfortable in low light.
