You need 2,000,000 stimulation points for the last item which wins the game. It sounds like a lot, but by that point you’ll be generating an insane amount of points per second and passive consumption is worth more than clicking. It does get overwhelming, at one point I had to mute the sound for a minute or two before resuming.
