Could you build this?

Partial The single-player puzzle logic is straightforward, but cross-platform compilation via Kotlin Multiplatform across four platforms alongside real-time 1v1 multiplayer and anti-cheat validation introduces significant complexity.

What it would actually take: The stack relies on Kotlin Multiplatform (KMP) and Compose Multiplatform for Android, iOS, Web, and Desktop. Real-time 1v1 requires low-latency matchmaking servers (via WebSockets or Nakama/Agones), deterministic lockstep or state synchronization, and a backend verification service to validate board moves and deter tamper-prone daily challenge submissions.
