Super amazingly great thanks to my buddy Telemachus for curating this! :D
Welcome to Chain Rule, a game of quick thinking and reflexes. Add the last two numbers of the chain together, then add the ones digit of that number to the chain. Add forty numbers to the chain to win, and try for the fastest time! Beware: your game ends if you input three wrong answers or if the timer reaches 100 seconds. Good luck!
