Dan Gilbert has released an iPhone version of the beloved puzzle game Triazzle. It costs $3 (through August 7, when the price increases to $4).
Triazzle makes use of iPhone capabilities — puzzle characters animate and “come to life” when they’re correctly solved, and puzzle pieces can be touched and dragged into place, or tapped to rotate. You can store puzzles in “docks” when you’re not using them and shake any puzzle to solve it.
System requiremetns call for an iPhone or iPod touch running iPhone OS 2.2.1 or later.
