Nice game :) unfortunately, it has a serious bug - if you have more than 100 ladders, than you can only use the last stack, i.e. let's say you have 123 ladders, therefore you will have 2 stacks of ladders: 100-ladder stack and 23-ladder stack. If you use all 23 ladders from the latter stack, then you cannot use ladders at all. You will end up with 100 ladders which you cannot use. I hope you understand my clumsy description ;p
