About this tool

Sometimes you just need a fast, fair way to settle something, and this tool turns the playground classic into a screen every student can see. Choose to play against the computer for a quick warm-up, run it team versus team to decide who goes first, or lean on it as an impartial referee when two students both insist they called the desk first. The animation and result land in seconds, so it never eats into real teaching time. Pull it up whenever you need a decision nobody can argue with.
