OH OH, here's another idea for another version of Torturebox (Inspired by Neester when he showcases mods).
If you place a icon when the first loop plays, the mod punishes you, leading to a game over. And maybe hide the loop later in the mix, so you would have to figure out which is the first and second loop.

However some polos may have exceptions, like a bulid-up polo who CAN/MUST be placed during the first loop. Maybe put a little message to let players know.
I'll show you another idea in the replies.
