Gameplay
The player is shown a fly in a jar, and then told to make the number of flies either 7, 9 or 10, by pressing two buttons next to the jar. One of them has "+1" on it, and adds one fly to the jar. The other button has "x2" on it, and doubles the amount of flies. The player can press these buttons in any order, as long as it makes the number. For example, if the number of flies to get is 7, the player can press "+1, x2, +1, +1, +1". If the player has made the number of flies by the end, they win. However, if the player does not do this, then they lose.
