Cotrio for is a logic puzzle game by indie Polish developer Bartosz Białek.


Cotrio consists of over eighty puzzles involving manipulating numbers. The game takes place on a board with six round fields, which you need to fill with three random numbers so that the sum of the first two is the third one. When the calculation is arranged correctly, the field with the result lights up and you can focus on the rest. The puzzle is solved when the whole pyramid is filled with numbers.

Things are made more difficult by the fact that the fields next to each other cannot be filled with the same numbers, and each puzzle consists of a given number of calculations.


The gameplay of Aderyn's Cradle is based on various video game genres. At the start, you choose one of the available character classes with unique abilities. There are four open worlds to explore.
