About this APK

Mono is a game by Studio Ochna in the Puzzle category. It includes native code only for ARM 32-bit, so it won't run on 64-bit-only phones such as recent Pixels.

Since version 1.1, the minimum Android version rose from 2.3 to 6.0. It asks for 4 permissions, none of them sensitive. Compared with version 1.1, it adds 2 new permissions: “Advertising ID” and “In-app purchases”. The game offers in-app purchases through Google Play and can read the advertising ID that ad and analytics services use.

What's new in v1.4

Update 1.2 fixes some minor bugs.

Description

From the listing uploaded by “appupdater”.

Pressing a button turns itself and it's neighbors on or off! The goal of this puzzle is to turn on all the buttons. Each button behaves differently. The rule is that buttons near the edges will turn on or off. - Win stars to unlock more stages. - Three kinds of buttons: triangles, squares and hexagons.
