The name is a lie, and it costs people an hour.
Mine Cart Madness is not a speed level. There is no timer, no track to outrun, and no reward for going fast. It is a pressure-switch puzzle in which the mine carts are limited-use projectiles, and the skill being tested is sequencing.
If you are approaching these caves like a Donkey Kong Country mine cart stage, that is why you are stuck.
The three rules the caves never state
1. Every cart has a hit limit. Hit a cart and it rolls. Hit it again and it rolls further. Hit it too many times and it breaks. Progress is not “hit it until it works” — it is hitting each cart the exact number of times the solution requires, then leaving it alone.
2. Carts respawn. A destroyed cart comes back. That sounds like a safety net and is actually the core mechanic: several solutions require you to deliberately destroy a cart so it respawns in a better starting position.
3. You use carts to stop carts. A cart already rolling will not stop where you want it. You park a second cart in its path so it stops against it. This is the trick that unlocks every multi-cart puzzle, and it is not obvious from the first cave because the first cave only needs one cart at a time.
The named cave: Mine Cart Madness
Location: the basement of the eastern temple, past the bomb birds and the cultist fire summoners.
The final puzzle here handles three carts simultaneously, which is where most people stop. The reason it feels impossible is that the third cart is not part of the sequence you have been building — it is a blocker. Solve the first two as a pair, then treat the third as the wall that stops the second from overshooting.
Bring:
- A full water tank. The route depends on pressure bomb shots while you are riding a cart.
- The pressure bomb or grenade launcher, for the cracked blocks.
The cave that is actually harder: Tenacious Trollies
The West Desert has a second mine cart cave, and it is longer and less forgiving than the one with the famous name. The documented solution runs roughly like this:
- Break the block on the left with a pressure bomb, then roll the first cart right.
- Two carts appear — a lower one and an upper one. Hit the lower cart right. Hit the upper cart left, wait for it to land, then hit it right.
- Follow them down and hit both carts left.
- Ride them and pressure bomb the dirt block on the left.
- Destroy both carts before continuing — this is deliberate, so they respawn.
- Go back up and wait for both to reappear. Hit the lower cart right; hit the upper cart left, then left again once it lands.
- Drop to the lower cart and destroy it. When it respawns, hit it left. Follow it and hit it left once more.
- Two carts are now adjacent. Break the right one. When it respawns on the left, hit it left.
- Hit the right cart of the new pair left.
- Break the leftmost cart and wait for a replacement. Ride it and pressure bomb the cracked block on the left to reach the artifact.
Step 5 is the one people skip. Destroying both carts is not a mistake you recover from — it is the required move, because the puzzle is solved with the carts’ respawn positions, not their original ones.
What you get, and why it is worth it
- An artifact in the secret area inside each cave. Artifacts go to the laughing-skull vendor in El Machino for blueprint mods, and the collection milestones (6, 10, 21, 28) unlock the unique mods that shops do not sell.
- An upgrade cog at the cave exit, plus a second one above the West Desert reachable only by jetpack.
- Access to the Armory Entrance warp point, which is the practical reason to do the eastern temple basement at all.
That makes the mine cart caves one of the densest sources of cogs outside the map collectibles — 77 cogs are on the map and 7 are bought from the merchant, and the cave cogs are part of the 77.
The habit that fixes every cart puzzle
Before touching anything, look at the switches and count backwards. Ask:
- Which switch is furthest from a cart spawn point? That cart has to travel the longest, so it is the one you hit first.
- Which cart will overshoot? That is the one that needs a blocker parked in front of it.
- Which cart do you need to break, and where do you need it to respawn?
Then execute in reverse order. The caves are solvable in one pass once you know which cart is a projectile, which is a blocker and which is bait — and unsolvable by trial and error, because every wrong hit changes the board state permanently until a respawn.
