The current aim is to introduce a weekly puzzle. If you have any puzzles (or articles) that you wish to submit then you can try emailing webamster
Like the problem that we faced at Easter. This time can you find the bag of false coins. You have an old fashioned "weigh yourself machine" which will tell you how much you weigh to the nearest gram with for a single coin. The problem is you only have one coin of the right denomination.
There are 10 bags with many coins in them. All the coins in each bag are of the same type so either all fake or all real. Real coins weight 10g each and fake coins 11g. Can you find which bag contains the fake coins in one weighing?
