Click on the fidget spinner to spin it. The higher the level, the faster it spins per click. Press the space bar to instantly gain half of what you would get if you waited for the spinner to stop spinning. Click the upgrade button to upgrade your spinner to the next level.
The higher the level of your fidget spinner the faster it goes, and if you reach a certain level the sound and texture of the spinner changes. Everything was made by me, except for the sounds, which are from Scratch's sample sounds.
