Caldris
Caldris Support
Caldris uses Calculation solitaire rules. Fill four foundations by rank increments +1, +2, +3 and +4. Suits do not matter. The next required rank is shown above each foundation. Place the stock card on a matching foundation or in any buffer. Only buffer tops can move to foundations; buffers cannot exchange cards. Win by completing four foundations of 13 cards. A game is stuck when stock is empty and no buffer top fits.
How to play
Use Rules → Try the tutorial to learn interactively. Practice has Undo and Hint; Hint identifies a legal move, not a guaranteed solution. Some deals may not be winnable. The current game saves after every accepted move. Continue restores it; Retry this deal starts the same order again.
Daily uses a shared deal and changes at midnight UTC. Ranked games must be started from Global rankings, require a profile and connection, and have no Undo or Hint. The server verifies the complete action trace and computes a score out of 48. Equal scores share a rank. An expired ranked Daily can continue as practice.
Account and data
If upload fails, retain your online identity and choose Retry upload when connected. Do not reset local progress while a result is pending. Reset local progress removes device records but not server data. Delete online account requests removal of your current hosted identity and its results. Lost anonymous credentials cannot be recovered from another device.
If account deletion is interrupted, reopen the app and use Retry account deletion. After server confirmation is saved, device cleanup can finish offline. If no online identity was ever created, practice remains available. Keep app data until an unconfirmed deletion is resolved.
