Who's That Isaac?!

The game features a rooms/floors system based on the floors from the actual game - guessing items correctly will advance you to the next room and eventually to the next floor, until reaching The Void!

Difficulty varies as more items are guessed - silhouettes may appear randomly rotated or flipped, curses may appear, and more! Players may use various hints in exchange for a points penalty.

The following features are currently available:

All items and trinkets! All items and trinkets from The Binding of Isaac are included and may appear when playing. The same database is used as the one from the main website.
Character selection! A variety of characters from the base game have been adapted to have their unique perks and downsides.
Seeds! All runs are seeded in the same manner as the base game. Players may manually set a seed in order to get the same run, or play with friends to see who will do better!
Daily runs! A unique seed is generated every day at 00:00 CEST. All players across the globe will get the same run when selecting the Daily Run option, a run that can only be attempted once per day.
Blacklisted items! Certain items have been blacklisted and will not appear. This is mainly due to them having the exact same appearance when blackened, e.g. books and syringes.
Mod support! All Binding of Isaac mods available on the website are also available in the minigame.
Share your results! Results can easily be shared after every run - brag or show just how bad you did, it's up to you!
Easter Eggs! Sometimes, just sometimes... you may experience something weird.
