As the demand for an Etheremon is increased, you may fail to catch it. Hence, we add catching power to make it easier for you.

You can pay more than the value of Etheremon when you see it to make sure you can catch it successfully. The change will be added to your balance. For example, when you see a Cobrus it has price at 0.1905, you make a transaction at 0.2096. When your transaction is mined, the price is at 0.1906, so you will get a Cobrus and 0.19 ETH will be added to your balance.
