Higher or Lower

Two cards. The one on the left shows its number. The one on the right is hidden — call it higher or lower.

Get it right and it slides across and a new card deals in. Get it wrong and the run is over: one life, no timer. Your score is how long the chain got.

The stat is dealt at random — goals, games, transfer fees — and every card in a run is the same position, so it's a real question and not a guess at who plays where.
