RPCiege is an educational gaming platform featuring bite-sized Soroban smart contract coding challenges called skirmishes. Round 1 included five challenges teaching contract basics, string handling, testing, RPC data queries, and callback functions. Round 2 introduced five more challenges focused on pseudo-random number generation, execution variables, and byte array filtering. Players earn digital collectible cards for completing each skirmish, with leaderboards tracking progress.
