Tetris, the classic game we all know, has just gone on sale for $2.99. Tetris went on sale once in early June, but has otherwise held steady at $4.99. This is a great port of the game we all love for the Fire TV. I wrote a mini-review of the game the last time it went on sale. This is definitely one of those games that permanently stays installed on the Fire TV because it’s so easy and fun to play a quick game here and there.
