Compare your current ELO with players worldwide on Game Center in real time -- no peak scores, just the real you. Also in this update: - The engine has a name: Caissa, mythological goddess of chess - "Impossible" is now "Insane" -- because that is exactly what it is - Move indicators are now visible even in bright sunlight - Leaderboard colors fixed in light mode ## Apps similar to Chess | App | Rating | Price | Category | | --- | --- | --- | --- | | [Chess Puzzles Trainer](https://appshunter.io/ios/app/chess-puzzles-trainer/id6770581711) | — | Free | Games | | [Chess Puzzles: Daily Tactics](https://appshunter.io/ios/app/chess-puzzles-daily-tactics/id6771032011) | — | Free | Games | | [KuboRush: Block Puzzle](https://appshunter.io/ios/app/kuborush-block-puzzle/id6757385646) | 5.0 (1) | Free | Games | | [Chess Coach: Learn & Play](https://appshunter.io/ios/app/chess-coach-learn-and-play/id6762184175) | 5.0 (1) | Free | Games | | [Quick Chess: Tactical Puzzles](https://appshunter.io/ios/app/quick-chess-tactical-puzzles/id6760239560) | — | Free | Games | | [The Blind Number Challenge](https://appshunter.io/ios/app/the-blind-number-challenge/id6450614483) | 5.0 (1) | Free | Games | ## More apps by Daniel Ferrer Delgado - [Lucus Bus - Bus Lugo](https://appshunter.io/ios/app/lucus-bus-bus-lugo/id1611708157) - [Pomodoro Watch-App](https://appshunter.io/ios/app/pomodoro-watch-app/id1666168491) - [Rainbow Blocks - Puzle](https://appshunter.io/ios/app/rainbow-blocks-puzle/id6448851332) - [Train Memory Colors Game](https://appshunter.io/ios/app/train-memory-colors-game/id6449209904) - [Bricks - Game](https://appshunter.io/ios/app/bricks-game/id6450151920) - [Create your own Adventure](https://appshunter.io/ios/app/create-your-own-adventure/id6504160376) All apps by Daniel Ferrer Delgado: https://appshunter.io/developer/1611708160 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
