Object: Find the hidden rectangles.

It is recommended that you play the original game 'Rec-Tangles' first.
If you found 'Rec-Tangles' too easy, then 'Rec-Tangles II' is the right game for you.

Click the board anywhere to let the system design a random setup for you.
The board is divided into smaller rectangles (plus a few single squares marked by black balls), but all the information of the rectangles is lost. Only their sizes are visible.

Create a rectangle by clicking what you think is its top left and bottom right corner position.
A rectangle must cover two or three numbers, and two of these three numbers must be the width and height of the rectangle you create.

If you cover more than three or less than two numbers, you lose.
An explanation text for your loss will appear on the lower border of the playing board.

You win when you have filled the board with rectangles.
This does not have to be the design that the system has created for you; other solutions might be possible and will be accepted by the system.
All setups are solvable.

The rectangles you create are coloured blue, red or yellow (alternatingly).
The colours have no special importance, but they make the finished games look pretty.

Variants:
In variants 6c,6d,8c,8d,10c, and 10d the black filler-balls are invisible. This makes the game more difficult.
Here your rectangles have to cover all numbers, and the gaps on the board must be isolated squares.
In variants 6b,6d,8a,8d,10a and 10d the fake rectangle sizes (which are to be ignored) range from 1 to 5 only.

Please note that there is an alternative piece set available.
