You can learn both systems, and switching between them is safe by design: progress in each is kept separately, so nothing is overwritten or lost.
-
Open Settings.
-
Find the bidding-system row: it shows the system you’re in now.
Step 2: your current system, shown in Settings. -
Tap it and read the confirmation. It says what actually happens: your lessons, practice hands, Daily Deals and quizzes switch to the other system’s versions, your old progress is kept exactly as you left it, and your streak carries on regardless.
Step 3: the confirmation spells out that nothing is lost. -
Confirm. The app switches on the spot.
-
Switch back whenever you like, the same way. Each system’s record is waiting exactly where you left it.
