To check your transactional history, you must press your current amount next to the deposit tab, then Account (For mobile press current amount > Account > The 3 stacked lines on the top left corner of the screen)
Once you do that, select the second tab named Transactions. You will find every financial action made by you, from bets to spins, in our slots and the current amount of information with a Deposit and Withdrawal option. You will also see an incognito option.
No worries, you can filter all this information by pressing one of the 6 tabs found next to the Data download option.
What you can see here is all the activity in your account.
You can also filter to see only bets, deposits, withdrawals, Golden Chips or others (you will usually be able to see the bonus amounts added to your account).
You can see data of the past one year.
