itch.io

It does, you are quick!

I found it! If you click with both of the mouse button at the same time it happens( for every buildings

I had 64 quartz when I clicked on it and it was unresponsive, I had to refresh the page for it to work   ; I have an habit of spam clicking, so that might have caused the issue,(maybe I  accidentaly clicked on the item menu on the top right  or the achivement thingy while it was spining)

I tried to use it in a single session like you suggested, but after a while it just stopped working(the slot machine)

Jokes aside, this is a great game

now at 1500+ with only a big win, perhaps I should actually play the game

I hate this game, unable to progress because of the gambing machine, spent 500+ gems in it and I have not hit a jackpot (higher than a medium win)... Would play again
