Show HN: I designed a math boardgame. HTML mock-up is now a playable game

Think scrabble/upwords but with simple equations and pemdas rules. My goal is still a tangible board game and your playtesting will help immensely. My html mock-up PoC has become a fully-fledged two-player networked or "solo play" solitaire game. It's "desktop-first", but is playable on mobile in landscape mode. Best solo game thus far is 4000+ with 38 tiles left in the bag. I have no doubt some of you will best that. Feedback is greatly anticipated and welcomed! Thanks for checking it out.
