About this game

One hundred problems that only thinking solves.

■ What kind of problems
These are not reflex tests. They are solved with reasoning, drawn from twenty categories: logic, probability, geometry, counting, winning strategy, ciphers, lateral thinking and more. The Monty Hall problem, the bridge and torch, weighing puzzles, river crossings.

■ Rank match, twenty problems
Twenty problems of mixed difficulty, easiest first, ninety seconds each. Harder problems are worth more, and answering quickly adds a time bonus.

■ Your rank card
When you finish you receive a Latin rank based on your score. Seven steps from TIRO through DISCIPULUS, ADEPTUS, PERITUS, DOCTUS and MAGISTER up to SUMMUS. It describes how your mind works, shown with the percentile you reached.

■ The solutions are the point
Every problem comes with the reasoning behind the answer and the place where most people slip.

■ Also included
· Daily three — new problems every midnight
· By category — clear all twenty categories
· Records stay on your device
· Ten background tracks and sound effects, both can be turned off
100 logic problems that reward thinking. Twenty of them decide your rank.
