Goblins
Goblins pop out of the barrels and duck straight back in. Hit as many as you can before the time runs out.

The rules
How you play
A goblin pops out of a barrel and stays out for a moment. Tap it — or click it — before it ducks back in and that is one more. Hitting one that has already gone does nothing: nothing is taken away and no turn is lost. There is nothing to lose here, only how many you caught.
The difficulty
It changes two things at once: how many barrels there are and how long each goblin stays out. On hard there are sixteen places to watch and each goblin is gone before you have finished deciding — which is why you play it by watching the whole thing rather than barrel by barrel.
The scoreboard
How many you caught is saved, and compared against the same difficulty and the same length. Thirty seconds on easy and sixty on hard are two different games, and mixing them would make a table where the winner is whoever chose best rather than whoever played best.
Played alone
This table has one chair. There is no entry fee, no chips are dealt and no points are scored: it is for the fun of it, and for the table.
