Little Inferno

Little inferno is a game about burning things. Almost the entirety of the game is spent in a first person view staring into a fire place. By burning things you earn coins to buy bigger and more interesting things to burn, with a focus on finding combinations of different items for "achievements" such as
"Spring time" for burning flower seeds and a clock, or "Movie Night" for corn on the cob and a television.

The fire , whilst not strictly realistic is certainly believable. It spreads between objects and after a certain amount of time break apart at stress points showing the physics engine they were built around.
