Free to playFrostrain The last train out of the ice
Your cars are your deck: draft new ones in cities, merge duplicates to strengthen them, and stack synergies to keep happiness up while a storm chases you toward the Promised Land in the east.
Is Frostrain worth it?
Frostrain is worth it if…
- you like deckbuilders where merging and synergies do the heavy lifting
- you want short roguelike runs you can replay in one sitting
- you like trains, snow, and bleak end-of-the-world road trips
- you enjoy figuring out systems with little hand-holding

Build a train that keeps everyone alive
Your deck is a line of train cars, and every stop is a draft. When you pass through a city, a heavy lift drone brings a choice of new cars, and you pick the one that fits your plan. Matching cars merge into stronger versions, and cars that share a color or group pay off together, so stacking the right set matters more than grabbing good stats alone.
Happiness is your health bar. It drains as you travel and in harsh ground, and cars refill it. Let it run out and your passengers throw you off the train. You route around the map, chase glowing nodes for extra cars, gain levels for more couplings, and try to outrun the storm to the east.
A short, sharp run through snow and poison
The world is white, frozen, and oddly pretty to cross, with toxic zones in your path and a storm building behind you. The trip to the Promised Land takes around half an hour when it clicks, which makes it easy to try another combination right away.
Three conductors change the starting setup, and unlocking the next one takes wins with the last. Some sets are easier to assemble than others, so early draws shape the run: a smooth academy start feels very different from scraping together an odd mix. The tutorial explains little, so expect your first run to be part learning, part experimenting.
Good to know before you board?
How do you actually lose a run?
Through happiness, which works as your health. Travel and bad terrain wear it down, and your cars build it back up. If it hits zero, the passengers revolt and your run ends, so route for cars and synergies that keep the number healthy.
What happens at cities and map nodes?
Cities let you add cars to your train by drone, usually as a choice of three. Normal stops give one car, glowing stops give two, and larger stops hold events. Leveling up from travel adds more slots to connect cars, so longer routes can support bigger combinations.
Is there combat?
No. There are no turn-based fights, enemies, or bosses here. The pressure comes from the draining happiness meter, toxic areas, and the storm behind you, while you manage the route and the train itself.
How long is a run, and what carries over?
A winning trip is short, roughly half an hour once you know the systems. The map and its events stay the same between runs, so variety comes from car drafts, merges, and synergies.
