Start your builder account
An account holds your builds and your tweaks. First stamp is on us.
Pick a part
Games and apps ride the same line — one shelf of parts, same gate, same stamp.
Your bench
Your tweaks
Your first stamp is free. After that, each stamp — a new build or a fresh version of one you own — takes 1 tweak. Tweaks never expire.
Tweak pack — 10 tweaks · $9 · never expire
One pack serves every part on the line — tools and games alike. Packs stack: buy two, get twenty. The tweaks land on your account the moment checkout completes. Packs live on builder accounts, so there's no guest checkout for them — you're signed in, you're set.
