Other worlds
Titan: where the rain is methane.
Saturn's largest moon is the only other world in the solar system with stable liquid on its surface. It runs a complete three-phase cycle — just not with water.
The same four steps, a different liquid
Everything the water cycle does here, methane does there. The difference is the temperature it takes to do it.
Evaporation
Liquid methane on the surface absorbs energy and rises as vapour, exactly as water does on Earth — but at around −179 °C, where water would be rock-hard ice.
Condensation
The vapour cools as it climbs and condenses into droplets, forming clouds in a thick orange haze of nitrogen and hydrocarbons.
Precipitation
Those droplets fall as methane rain. Titan's gravity is about a seventh of Earth's and its air is dense, so the drops fall slowly — far more like drifting than the downpour you know.
Collection
What lands gathers into lakes and seas large enough to have been named and mapped, ready to evaporate again. The cycle closes, with no beginning and no end.
What that means for the game
Titan is not a reskin. The rules change because the physics changes.
A colder, slower world
The palette shifts to the orange haze of Titan's sky, and the falling drops behave differently. This is the world the game's Titan track and its own trivia set belong to.
Three phases, not two
Methane on Titan exists as solid, liquid and gas in the same way water does here. That is the whole reason Titan is in a game about the water cycle: it shows the cycle is about the substance meeting the right temperature, not about water being special.
Earned, not bought
Titan unlocks free by finishing all sixty-six water-cycle questions with thirty or more correct. It is the reward for learning the Earth cycle properly.
