Well, I'd say that's close to a 1 grand prize per tool kit. You used less than half a tool kit of brushes, half a toolkit of shovels, but 75% of dynamites. I'd say a bit over half a kit for slightly under half a grand prize, but still not far off.Only I I'm unlucky? 9 idols for 7 brushes, 4 shovels and 6 dynamite? Or you and osserc are lucky?

If you're interested here's a video of me doing the Halloween event. Watching it back I definitely make some mistakes (using too many candles early on), but I do get around 1 grand prize per tool kit:
