About this deal
But wait, there is more. One of the protruding sides of each puzzle piece has 1 ball (A), the other side has 2 balls (B). So depending on how you orientate the puzzle piece, you get a puzzle piece with more or less visible balls. The game board has a grid with 50 holes. And all holes need to be covered by puzzle pieces. So if you start with puzzle pieces with a lot of balls, you might have puzzle pieces left over at the end with too many balls that don't fit. Or visa versa, you don't have enough balls to cover all holes. This is what really differentiates this game from all other 2D assembly puzzles. There are 120 challenges in this game. I started with 100 challenges, just like I did for IQ-Twist. But some people (and kids) found the first level of that game too difficult to start with. So we created 20 extra challenges for IQ-Fit that are very, very easy. So for puzzle experts the number of "real challenges" is 100. Because you have 10 puzzle pieces with 2 different sides, there are in fact 20 different possibilities to choose from. You might think that this will lead to many solutions, but every challenge has just one. That is also different from the original IQ-Puzzler (not the newer PRO version), where most challenges have several solutions. The easiest challenges show you the position and orientation of 8 puzzle pieces, the hardest challenges show you only 2.
