Invisilink

Do you have what it takes to play the classic 4-in-a-row game with hidden blocks

Play the classic four-in-a-row game with invisible blocks!

Four-in-a-row, also known as Captain's Mistress or Connect Four, is a simple strategy game played in childhood. Invisilink raises the stakes by hiding blocks, making the game a test of your memory and concentration, as well as four-in-a-row strategy!

This game features 3 modes:

* regular, where all the blocks are visible

* one-colour, where all the blocks turn the same colour once dropped

* invisible, where all the blocks are hidden from view!

The game also features 3 AIs to challenge you, random, medium, and hard. In the one-colour and invisible game modes, any of these will be enough to test you!
