Blindfold Connect

Blindfold Connect is an fully accessible audio game, inspired by the puzzle game Connect Four.

It's a two-player connection game in which the players first choose a color and then take turns dropping colored discs from the top into a seven-column, six-row vertically suspended grid.
The pieces fall straight down, occupying the next highest space within the column.
The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own discs..

Blindfold Connect was suggested by several blind gamers who enjoyed Blindfold Sound Search.

The game comes with coins; you need one coin to play. More coins are available as an in-app upgrade.
