Cookie clicker! Click for cookies, press space for clickers (each one costs 50 more than the last)

Show more comments…
u/KilledByAPixel

awesome! i was confused at first, you need to click 50 times before you can click space to buy an auto clicker.
u/katkip

Awesome!
u/lionleaf

Awesome! Pressing space scrolls the page down though :(
u/lionleaf

I've spent way too much time on the original cookie-clicker... I'd also recommend the paperclips game
u/lionleaf

#game #interactive
u/13thptr

u/lionleaf play fullscreen :)
u/mildlybean

I love the paperclips game
u/katkip

tycoons are boring and fun in the same time
u/lionleaf

I got to 600M cookies and now have 7k clickers. Turns out at some point it starts becoming possible to go negative as well. Currently at -130M #cookie #cookie_clicker
u/awareness481

You have 2 characters left. You can use those to cover any number overflows :P

Clock

Nice one. Can use this to demonstrate that JS uses the client's local environment clock

Made some room for more features

u/lionleaf

Nice! Found a bug: You lose 1 cookie even if buying a clicker fails.
u/DataMeta

It's the bug that eats the cookie!
u/veubeke

@lionleaf: you’re right, replacing || with ?0: fixes that
