What's New in Chessdoku
1.1.0
September 4, 2026
Chessdoku 1.1 sharpens the challenge and the teaching. • Real difficulty, every level. Each puzzle is now hand-graded Standard, Difficult, or Extreme — shown right on the level map — and every level past the intro is guaranteed to demand genuine deduction. No more trivial walk-throughs. • Hints that actually teach. Every hint now explains the deduction: which piece, which square, and exactly why it's forced — so you learn the technique instead of just being handed the move. • Daily reminder. Opt in to a gentle evening nudge so you never break your daily-challenge streak. • Smoother and steadier. Startup and save-data hardening plus a range of polish fixes. Still no ads, no account, no tracking — every puzzle generated on your device and provably solvable by pure logic.
