The following three games are downloadable flash games so you will need a flash program installing. You’ve probably already got one installed, so try playing the game first. If you haven’t you can download Adobes flash player from the following link:

Let it Flow:
This game was made for free to support UK’s red nose day. Rotate the pipes so that they connect from the pump to the crops and animals before the time runs out. Watch out for spillages, and don't forget to pump the water to get it moving. One of the most popular flash games ever. It's had millions of plays worldwide.

Trimanic:
Trimanic plays like Lumines plus Bejewelled plus triangles plus huge spinning disc. Players spin triangles around to make big triangles of the same color. Try making many triangles of the same color in a row to create huge combos.
The developer says that the game is still very early in development and needs to be rewritten. Still, I though it worth posting here.
