Hello. We don't have guides related to the process of creating a game based on Waves blockchain and powered by Smart Contracts.
Firstly, you should get acquainted with Smart Contracts and its features within the Waves ecosystem via our documentation: https://docs.wavesplatform.com/en/technical-details/waves-contracts-language-description.html
For all specifications concerning the process of development, feel free to join our Discord server: https://discordapp.com/invite/cnFmDyA #development channel  and Dev section on the official forum: https://forum.wavesplatform.com/c/developers

Best wishes,
Waves Community Manager
