Hexcells

Hexcells is an ambient puzzle game that combines elements from Minesweeper and Picross. The goal is to clear a board of adjacent orange hexagons by uncovering them, revealing a black one with a number or a blue one by clicking left or right respectively. Each board contains a set number of blue hexagons shown in the top right corner. Through math, deduction, exclusion, and uncovering the board from different directions, you need to reveal all hexes with as little mistakes as possible.

A simple board generally provides a number of black hexes with a number inside. This number tells you how many blue hexes are connected to any of up to six possible sides. There is always a logical solution to progress without guessing, but often certain parts of the board need to be cleared to receive enough information to solve another part. For instance, a hex with a one inside signifies that just one of the six possible linked hexes is blue. If the blue one is found, you know for certain that the other five are black. There are also hexes with a zero inside, meaning all surrounding ones are black. Boards do not always form a single field, often they are made up out of small islands and the borders help to narrow down the possible options.
