These are some other things I try to do when bored:
a) Go through each of the hards other than | and @ without guessing. Take as much time as you like, but dont click anywhere unless you can see in your mind that it's a correct move. If you get stuck, keep trying to figure out what can be done, and what can't. This can be a great way to learn patterns. Not all boards can easily be done, so it may take a few attempts, but I can usually get through all 8 eventually.
b) Try to do a board with as few right clicks as possible. Here are my records:
| Board | Right Clicks | Seconds | Date | |
| Gero | He | 1 | 5 | 15/04/05 |
| Q | He | 1 | 6 | 07/04/05 |

Some of my best times were done right after a few attempts at this, including my 42 seconds in Hh
