Am impressed by your WP and hopefully it will be viable and delivered beyond the scope in terms of scaling.
appreciate your feedback fromcoins, for chess, othello, delivery and scalability is not an issue, since most of the verification is happening off-chain.
For 'harder games' like poker, will have to spend more efforts on an efficient implementation.
Please kindly check out below link on the implementation challenges, Thanks !
