My friend Abhay Kashyap and I have recreated the game AddEmUp! It was a flash game, so you can’t play the original any more. Link: https://addemup.abhayandsimon.repl.co
After Adobe first deprecated and later blocked Flash (old software), many classic nerdy games became unavailable. Simon and Abhay devoted their latest couple of collab sessions together to help one of those classics from oblivion, a tricky arithmetic puzzle game called AddEmUp. Below are some screen shots of the workflow.
