Daily challenge

Every day one of the trainers comes up, and everybody who plays that day gets the same game and the same questions in the same order. It is a short run, so it fits in the gap before whatever you were about to do, and it is the same short run for the person you are arguing with about bollards.

How it works

The game and the question order are worked out from the date itself, so nobody picks them and there is nothing to look up in advance. Every trainer takes its turn before any of them comes round again.

A day can be played once. Leaving halfway through is fine: come back and you pick up where you left off, on the same questions, because they were never anything but the date. Finish it and that is the day's score, so it is worth taking the first attempt seriously.

Your streak, your scores and your history live on this device and go nowhere else. There is no account, and clearing your browser data clears them.

Games in the rotation

Any of these can come up, and new trainers join the rotation as they are added. A game needs enough subjects to build a run out of, so the very smallest ones sit this out.
