Implementation
Not only did this agent include the crucial “chording” feature, but it also included on-screen instructions for using it on both PC and mobile browsers. I was further impressed by the option to cycle through “?” marks when marking squares with flags, an esoteric feature I feel even most human Minesweeper cloners might miss.
On mobile, the option to hold your finger down on a square to mark a flag is a nice touch that makes this the most enjoyable handheld version we tested.
Presentation
The old-school emoticon smiley-face button is pretty endearing, especially when you blow up and get a red-tinted “X(“. I was less impressed by the playfield “graphics,” which use a simple “*” for revealed mines and an ugly red “F” for flagged tiles.
The beeps-and-boops sound effects reminded me of my first old-school, pre-Sound-Blaster PC from the late ’80s. That’s generally a good thing, but I still appreciated the game giving me the option to turn them off.
“Fun” feature
The “Surprise: Lucky Sweep Bonus” listed in the corner of the UI explains that clicking the button gives you a free safe tile when available. This can be pretty useful in situations where you’d otherwise be forced to guess between two tiles that are equally likely to be mines.
Overall, though, I found it a bit odd that the game gives you this bonus only after you find a large, cascading field of safe tiles with a single click. It mostly functions as a “win more” button rather than a feature that offers a good balance of risk versus reward.
Coding experience
OpenAI Codex has a nice terminal interface with features similar to Claude Code (local commands, permission management, and interesting animations showing progress), and it’s fairly pleasant to use (OpenAI also offers Codex through a web interface, but we did not use that for this evaluation). However, Codex took roughly twice as long to code a functional game than Claude Code did, which might contribute to the strong result here.
