Solo dev here, I made this. Sudoku is usually a solo thing, so there's no easy way to see how you compare. So I built Sudoku Throne around having an opponent. - Speed : you and your rival get the same puzzle, first to finish wins. - Items: fill a gauge, pick one of three items, and freeze or fog your rival (or shield yourself). - Cell Race : one shared board, three minutes, whoever claims more cells wins. A wrong digit locks your input for one second. There's always a ghost opponent, so you don't wait for matchmaking, and you can play friends in real time. If you just want to solve alone, there's an adventure through nine countries and a training area that teaches techniques step by step. After ten versus games you get placed into a tier, Bronze to Master. Full disclosure: the clip was recorded with an auto-play switch I built for filming, so that's not my skill on screen Android & iPhone: https://ieumapp.com/sudoku/get?src=reddit What would make you keep playing a Sudoku like this?   submitted by   /u/zzoa7922 [link]   [comments]
