Do you like physics games? I sure do. Puddle THD happens to be a great game in this category if you happen to have a Tegra 3 device. The puzzle-centric fluid simulator is typically available on the Play Store for $5, but today the app has gone on sale for a measly $0.99 to celebrate its first whole year on the market. Not bad!
To get an idea of what this game is like you can either watch the video above or rely on my words.
