# Increasing Gas Fees

In games where the prize pool becomes significant enough, some participants may engage in what is known as a "Blockstuffing" attack. This is when many transactions are made which fill multiple blocks, and stop others from including transactions in the chain within a certain period of time.

This can be addressed by increasing the gas fees paid when making a transaction, in order to guarantee inclusion in a block even if an attacker is attempting to fill it with their own spam transactions.

In the final minutes of a game, the Yeet modal that appears will look like this in order to warn users:

It is recommended to try make a transaction normally, and if it fails, to increase gas fee to the recommended amount.
