Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• New mode: 2-4-6 — probe integer sequences to discover the hidden rule, then build your guess from chip-shaped predicates and submit. Five verdict states (solved, equivalent, close, etc.) with rating and a probe trail
• Knights & Knaves: added a Share button to the result screen so you can post your solve time and proposition count
• Display name screen: added a "Login Instead" option for players who already have an account on another device, so they can sign in without first picking a throwaway name
• Knights & Knaves: changed the guilt constraint wording to "The person/people who committed the crime are a knight/knave" so it's clear the constraint covers one or more guilty parties
• Tutorial: added 3 sanity-puzzle levels covering the four type/sanity combinations, belief statements, and a conditional that pins both axes. The K&K tutorial is now 16 levels
