An item quiz for The Binding of Isaac, covering every item in Rebirth, Afterbirth, Afterbirth+ and Repentance - 719 of them. It tests whether you know the item pool, not whether you can look it up.

SIX MODES

Daily - one item a day, the same for every player. Six guesses. Each guess is scored against the answer's version, quality, type and item pool, so every wrong guess narrows the next one.

Grid - nine cells to fill. Every answer has to satisfy both its row constraint and its column constraint. Six hearts; a wrong answer costs one, a hint costs none. Filled cells are coloured by how rare your answer was among everyone who solved that cell.

Draft - five rounds. Each rolls an item pool and a game version; name an item that belongs to both. The run is scored on the mean quality of your five.

Name It and Find It - ten items against the clock, from icon to name and from name to icon. A perfect run posts its time to the leaderboard.

Wiki - all 719 items, searchable and filterable by pool, quality, type and version.

The five game modes each have a normal and a hard ruleset. Hard removes the safety rails: the daily refuses a guess your board has already ruled out and gives no reading for it, the grid locks a cell on a wrong answer, the draft hands you the whole item table instead of a filtered list.

Leaderboards are ranked for every mode, normal and hard together. Stats keep your guess distributions, win rates and streaks on the device. No account and no sign-in; an anonymous id is all that leaves the phone. Free, supported by ads; a rewarded ad buys a lookup, a practice run or a streak patch, and a short ad plays at the end of a run.
