 # Best Practices
 
+## Limit gas usage on the callback
+
+Keeping the callback function simple is crucial because the entropy providers limit gas usage.
+This ensures gas usage is predictable and consistent, avoiding potential issues with the callback.
+
+For example, if you want to use entropy to generate a random number for each player in a round of game,
+you need to make sure that the callback function works for the maximum number of players that can be in each round.
+Otherwise, the callbacks will work for some rounds with fewer players, but will fail for rounds with more players.
+
+Multiple solutions are possible to address this problem. You can store the random number received from the callback and
+either ask users to submit more transactions after the callback to continue the flow or run a background crank service
+to submit the necessary transactions.
+
+The gas limit for each chain is listed on the [contract addresses](./contract-addresses) page.
+
 ## Generating random values within a specific range
 
 You can map the random number provided by Entropy into a smaller range using the solidity [modulo operator](https://docs.soliditylang.org/en/latest/types.html#modulo).
