I went trolling for logic games and caught Discovery Education's Brain Boosters
Brain Boosters is a source of numerous challenging brain puzzles for all grade levels. The archive of puzzles is large, well over 200, and categorized by type of puzzle: categorization, lateral thinking, logic, number and math play, reasoning, spatial awareness, and word and letter play.
I used many of the puzzles from the logic and reasoning categories as daily starters in my geometry classes. The puzzle was on the interactive whiteboard as kids came in and began to talk and think about it.
As you see in the above video, each puzzle is accompanied by a detailed explanation of the solution. You will also find a button above each Brain Boosters puzzle to easily share the puzzle via MySpace, Facebook, Twitter, and more.
