Hi. We're sorry about that. When playing in the browser, data is stored only in it and until the cache is cleared. Data cannot be restored now. You can run the game on android (the data is stored there until you delete the app).
Previously, saving/loading was added, since after updating the game, all the player's progress was reset. Currently, when updating the game, the progress is not reset, so saving/loading is disabled.
At the moment, in the web version of the game, diamonds can only be obtained in the Challenge mode. Later we will add other activities in which diamonds are issued. In the mobile version of the game, you can buy crystals for real money.
The game has both bots and real games. Since there are few real players, bots have been added to the game. To have more real players, bring your friends into the game.
