There are many reasons for the inaccuracy of your chips. Sometimes there is a lot of traffic on the games offered by the casino, resulting in a delay in recording losses and wins on the casino’s servers. Updates sometimes take up to an hour.
Payouts can also get complicated and you may end up with the wrong chip total than you expected after a big win.
If you notice an inaccuracy in your chip total, contact the casino’s customer support with the necessary information so that the cause of the miscalculation can be investigated and resolved.
