Split Decisions is a word game played in a grid with twenty one split cells. Each cell presents you with a choice of 2 letters. To win the game, you need to select the correct letter in each split cell, spelling out the six hidden words.

This is the VB.Net version, but I have also uploaded a C# version here in the Wiki Gallery (link provoded at bottom).
