Collecting enough of the game's glowing yellow Lums in a stage earns you a scratch
card that in turn unlocks classic levels from Origins (there are over 40 of these), bonus Lums (your cumulative total of which opens up more content) and even weird
little pet creatures (pigs,
robots, pieces of toast) which generate more Lums every day.
In
Little Inferno you burn flaming logs, screaming
robots, credit
cards, batteries, exploding fish, unstable nuclear devices and tiny galaxies.
