Answering the same puzzle multiple times is by design: most of them randomly generate (except meaningoflife). And in theory our algorithm scales your reward based on the real-world difficulty of the problem. I'm sure it will take some tweaking, but it looks like meaningoflife is handing out 5-10 sickles at the moment, spiralling downward with each solve, while the resistor lattice is in the hundreds of sickles.
Sickle balance is on the page footer. Did you miss it? Should we move it to the top somewhere?
