More play. Less guesswork.

In Settings, Progress backup saves only the current player shown on screen. Keep a separate file for each player. When importing, check the name and summary: restore replaces the current player’s progress without merging; other players stay unchanged. The recovery copy belongs to the same player. Language, appearance and accessibility remain shared. Export before uninstalling.

Open Local players in Settings. Main player keeps existing progress; Guest and added players have their own games, lessons, rivals and favourites. Guest keeps progress for the next visit. Leave the game before switching. Archiving keeps the data and lets you bring a player back. Profiles have no passwords: anyone using this device can open them.

In Play, choose “2 players”. Play without a clock, with 10+0 or with 10+5, and optionally rotate the board after each move. The game has its own save; leaving it or putting the app in the background pauses it. Local games do not award bot campaign victories.

Yes. Rivals, the campaign, analysis, 365 daily puzzles and 120 extra exercises are included. No account is required.

In Challenge, defeat rivals in campaign order. Training lets you practise against all standard rivals. The King of Chess appears at the end of the path; unlocks earned in earlier editions are preserved. Your collection offers clues for secret characters.

Your device’s local date selects a puzzle. The 365-position collection then repeats. The calendar offers available past days; future days remain locked.

A hint shows the piece to use. Seeing the solution before solving marks the day as explored, without solve credit. Medals reward 1, 7, 30, 100 and 365 solved days. Breaks never remove them.

Open the analysis of a completed game. When enough moves have reliable evaluations, valid practice positions are saved. Your rematch offers up to three. Correct first attempts return after 1, 3 and 7 days. Help or a wrong attempt schedules the next day. Scores and rival strength stay unchanged.

On this device. KreerIQ does not sync progress between phones. Updating the same app normally preserves progress; uninstalling or clearing app data can remove it. System backups depend on your device settings.

Use the PGN export in a game. It saves the moves, not a backup of your campaign or medals.

Note the app version, device model and steps that caused the problem. A screenshot can help; check that it contains no personal information. The app never automatically sends your game history to support.

This edition is offline. Online duels and tournaments are future directions, with no availability date announced here.

10+5 adds five seconds after each completed move. Choose 10+0 for ten minutes without an increment. In a timed Challenge against a rival, leaving the app does not stop the clock. The 2 players mode pauses when you leave or put the app in the background.

Open Practice for chess lessons, guided endgames, daily and free puzzles, Puzzle Sprint and royal challenges. You can also practise a position from a finished game or an imported PGN.

No. Their short reactions, stories and English voice clips are included on the device. In Settings → Rivals, adjust dialogue and voices. These conversations do not record your voice or send messages to an online service.

Open Settings → Accessibility. The option is off by default. It adds English descriptions and text move entry for use with your device’s screen reader. Return to Settings to turn it off.

Check the game’s sound settings, rival voice settings and your device volume. Rival voices pause during background use and do not compete with the screen reader. The opening logo follows the game sound setting.

Keep the original file. Use an app version at least as recent as the one that created it. The app checks the file and shows a summary before restoring. Cancel if the player or contents are wrong. A failed validation does not replace your progress.
