Science-based tactics training with spaced repetition — built around your games and your weaknesses.
Connect Chess.com and we analyze your blunders, then build a personal puzzle queue targeting your exact weaknesses — not generic positions.
The SM-2 algorithm shows you the right puzzle at the right time. Nail a pattern and it fades from your queue. Miss it and it comes back tomorrow.
28 tactical patterns across 3 tiers — from forks and pins to windmills and zugzwang. Track your weakness per pattern, not just your overall score.
Start free. Upgrade when you're serious.
Yes. The free tier gives you 10 puzzles per day and full access to Tier 1 patterns — no credit card required, ever.
Chess.com shows you random puzzles. We show you the puzzles you need based on your actual game history and spaced repetition science. We're not competitors — we're complementary.
It's a learning technique backed by cognitive science. You review material at increasing intervals — right before you'd forget it. The SM-2 algorithm (used by Anki) optimizes this timing automatically.
No. You can train with the full puzzle library without connecting Chess.com. The Chess.com integration just lets us personalize your queue based on your actual blunders.
