Battle modes are not available right away and need to be unlocked by playing matches in League mode to reach the required level. Each battle mode unlocks at the following levels:
•Count Up is unlocked at level 7
•Shanghai is unlocked at level 12
•Cricket is unlocked at level 18
To unlock the higher stakes of these game modes you must win a certain number of matches in the previous stake of that battle mode. For example playing 20 games of Count Up in the 500 coin (Standard) stake unlocks the 2000 coin (Golden) stake.
To unlock the Golden stake in each game mode you must win 20 games in the Standard stake. The final stake, Diamond stake, is unlocked once you’ve won 80 games in the Golden stake.
Alternatively you can unlock Golden stakes in each game mode for 600 gems, and Diamond stakes for 800 gems.
