Turn every puzzle into progress. Train with 5M+ puzzles from real games, personalized to your level. When you make a mistake, understand why - and learn from it. That’s the idea we built this app around. Solving more puzzles is useful, but we wanted training to be about more than getting a position right or wrong. We wanted every puzzle to teach you something - about the move you missed, the pattern you didn’t recognize, or the way you calculated the position. There are more than 5 million puzzles from real games. But the number itself isn’t really the point. What matters is finding the right positions for you, at the right difficulty, and helping you learn from them. When you make a mistake, you can understand why. Use hints, explore better moves, get coaching, and look deeper into the position instead of simply moving on to the next puzzle. Over time, your training starts to reveal which tactical patterns give you the most trouble. You can practice across 64 motifs and patterns - forks, pins, sacrifices, checkmates, endgames, and many more - and spend more time on the ideas that need it. You can also see how your training develops over time: your rating, accuracy, training time, and performance across different patterns. And when you’re ready for something truly advanced, there are more than 300,000 composed chess problems from solving competitions. They’re difficult, precise, often beautiful - and solving them can be one of the most satisfying forms of chess training. We’ve also tried to make this a place you’ll actually want to come back to. Solve a few puzzles when you have five minutes. Sit down for a longer session when you feel like training seriously. Build a streak, reach a milestone, or simply keep showing up. Whether you’re new to tactics or have been playing chess for years, the goal stays the same: Learn something from every puzzle. Play better chess. And we’re here to help you along the way.

Verdict

The call

The clearest difference is ads: Chess Puzzles at none against Chess Prep Pro Openings's shown. Chess Puzzles also leads on update cadence (every 3 days vs fortnightly) and rating (4.8 vs 4.5). Chess Prep Pro Openings's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price, in-app purchases and monetization model there is nothing between them.
