Kuriorama: Logic Puzzle

Ball yes, dice no. What's the rule?

A conveyor belt brings objects, and two boxes wait below. Drag each object into a box and the game answers right away with a check or a cross. No text.

Behind it sits a rule nobody tells you. "Made of metal", say, or "round", or "fits in a pocket". Get five right in a row and the rule is revealed. Three crosses and the round is over.

WHAT'S DIFFERENT

In most sorting puzzles you know the rule and work through it. Here the sorting is easy. Figuring out the rule is the hard part. You watch, guess, throw ideas out. A cross brings you closer to the end of the round, but it also tells you something. With two guesses in mind, good players sometimes miss on purpose to tell them apart.

WHAT'S INSIDE

• 396 objects drawn in the style of old copperplate engravings
• 133 rules in eight chapters. In the later chapters the rule sometimes hides in the name of a thing
• Compound rules from level 3 ("round and hollow"), exceptions from level 7 ("everything except tools")
• The Codex: every rule you crack becomes a card with your first hit and how all players did
• After each round you see which objects you got wrong
• The sense rank: how many objects you need per rule on average
• The daily rule: one rule a day for everyone, one try. Share your result as a grid of squares without giving the answer away. Stats keep track of your streak, and you can turn on a reminder at 6 pm
• There is a tutorial, but the opening usually does it: ball, dice, ball

MADE FOR SHORT BREAKS

A round takes 60 to 90 seconds. You start with three lives, and each one comes back after half an hour. The game is meant for a few rounds a day. The look: paper, ink, museum lettering. Green and terracotta only show up as feedback, green for right, terracotta for wrong.

DIAMONDS AND LIVES

Diamonds are the currency. You earn them by cracking rules and spend them on lives, a hint or streak freeze. The lantern shows you one object that fits the rule. If you need more, you can buy diamonds. Or support Kuriorama once: you stop losing lives and get 50 diamonds on top. No subscription. The purchase belongs to your account and can be restored on a new device.

OFFLINE, NO ACCOUNT

The game runs on your device. No account, no tracking, no analytics. Only the daily rule comes from a server. Offline, the app works it out from the date.
