Unsure as to if this is intentional or not, but the credit amount displayed next to RPS is one bet behind.

If you were to bet 100 and lose the credits don't update unless you refresh, or bet again. Then the rest of the bets are always one bet behind, displaying the increase or decrease of credits from the last bet.
