Another one, "Flip and match" hidden entities. This game is available in various complexities, like easy/medium and hard, on board sizes 8*8, 10*10 and 12*12.

One more addition: Minesweeper! One can play upto 18*18 (on Firefox, and 21*21 on IE) on the space given. Enjoy. However, the algorithm can be bettered (for better boards) for sizes more than 10*10, will work on it later.

Flagging mines with right-click is not there yet.

New addition: Maze creator, a program that can create mazes (less than 100*100 dimensions). Try creating some and solving them.

Folks, try my new NumberDumber number puzzles collection. One can generate a puzzle for himself/herself to solve, or use the solver to get a solution to a known "digit arithmetic puzzle". Test your math skills.

For those of you interested in designing interior, there is a software called "Home Designer Suite", which is awesome. It can give nice images of 3-d interior, that one can design and see, by himself.

Sorry folks, I got into some Copyright issues with the originators of those interior photos, had to remove them from here. Sorry about it.

There is another small puzzle that I came up with, it is actually a trick question than a puzzle, and probably for school kids puzzles.

If you go from point A to point B (on road), by taking a right turn, and then a left turn, how do you come back from B to A? What turns will you take in order? (This can be asked as a quick reply question to folks, and see what they say? People say reverse, as in, "first left turn and then a right turn", which is wrong).
