HERE'S an interesting variation on the sliding block puzzle theme that we guarantee will keep you hooked for hours - if not weeks. The idea is quite simple. All you have to do is manoeuvre the large block on the left - marked B - fully into the flashing square on the right. At each move you will be asked for the letter corresponding to the block to be moved, and then one of the arrow keys to show which way it is to go. 
Can you crack Ian Sharpe's fiendish puzzle?
There is no time or move limit because the problem is difficult enough as it is. In fact we haven't even solved it ourselves, but we are assured that it can be done. ACU #8903 |
