43 is a puzzle game made by ICU Development Inc. In it, you match tiles until you get to 43. It's that simple.


You match tiles until you get to 43. You just go like this:

  • Two 1's means one 2.
  • Two 2's means one 3.
  • Two 3's means one 4.
  • Two 4's means one 5.
  • It goes like that until you get to 43.


The game received favorable reviews from most magazines, but ICN gave it a 9 for "its gud".

43 (series)

The game was followed up with a book series about being addicted to 43, called 44.

Another game was being made by the now-defunct ICU Development Inc., called 45, although it was cancelled just after E3.
