I built Chess Cubed with GPT-6 Astra in 4 days
A developer created "Chess Cubed" in four days using GPT-6 Astra. Astra assisted with 3D asset creation via Blender and MCP, web development using babylon.js, and mobile versions for iOS and Android in Unreal Engine, also with MCP. AI was also used for music and sound effects. The project consumed 110% of the developer's weekly usage on the $200 plan, including a reset from Tibo.

I’ve wanted to create a more complex version of chess for a long long time. More possibilities, more directions to think about, and threats attacking from all angles. I designed physical versions but always wanted a digital version.
With the release of GPT-6 Astra I thought I'd give it a go via Codex, and within just 4 days it brought my Chess Cubed idea to life. The game wraps around six connected faces on a cube, so strategy has to account for what’s happening around all sides. Pieces primarily move the same with minor modifications to accommodate for the multi-sided play.
I had Astra work across Blender vai MCP to create all the 3D assets, then created the web version using babylon.js, and then I wanted to bring it to iOS and Android so I had Astra build Chess Cubed in Unreal Engine also using MCP. I also used AI for the music and sound effects. Astra on xHigh used 110% (included a reset from Tibo) of my weekly usage on the $200 plan.
The game has single player versus CPU with multiple AI difficulty levels, full multiplayer capability - including chat, and multiple different skins. :)
Rules: standard piece moves, four extra pawns per side (for protection across multi-sided play), at most one edge crossing per move, diagonals max five steps, pawns promote in the opposite face’s central 4×4. Checkmate wins.
GPT-6 Astra is Amazing, thanks OpenAI. https://preview.redd.it/uscg6lgojioh1.png?width=2560&format=png&auto=webp&s=bb4228a6d92deb3613c3ecdf830f45cf5527ead7
