In the multiples of 5 levels, there are treasure chests which worth vastly more than all the other treasure, making it relatively pointless to waste dynamite on other levels getting at the much less valuable treasure. So long as you don't waste what you pick up in the intervening four levels, you have more than enough to keep going indefinitely (I typically use 5/6 dynamites and 1/2 maps in the tricky levels). where the level number is a multiple of 5) has so many traps that you'll need to use some of your axes/dynamite/maps to get through unscathed. Four out of every five levels can be completed using logical deduction only to find the way through to the exit (you don't need to guess or use pick axes/dynamite/maps).

After playing on for a bit (up to level 131 now) it seems that the levels just go through a fairly repetitive cycle.
