Thirteen is an unlucky number, and this little expedition game leans all the way into it. Every 13 seconds a curse grabs your explorer and sends their feet in random directions. Lost City of S unblocked asks you to keep walking north anyway, all the way to a hidden idol.
Markus Fisch made it for the js13k game jam in 2024, where the whole game had to fit in 13 kilobytes. It is short, cute and easy to finish in one sitting.
How to play Lost City of S
Your trip begins at the bottom of the map in thick jungle. Head north and the land changes from jungle to desert to water. Gorillas wander the trees, scorpions hide inside a stone maze in the sand, and piranhas dart through the lake near the end.
Rocks and boulders block your way, but trees and bushes are just decoration you can walk through. When an animal catches you, your energy drains. Lose it all and the explorer flops down for a moment, then gets back up in the same spot, so you never lose your progress.
Keep an eye on the ring of dots in the top-left corner. It fills once every 13 seconds, and when it closes the curse makes your next steps wobble. Reach the idol at the far north to finish.

Tips
- Pause before the ring closes. If you stand still in a safe spot as the last dot appears, the stumble can't throw you into trouble.
- Walk through the greenery. Only gray stones are solid, so cut straight through palms and bushes.
- Plan the maze in short hops. Scorpions are slow, but they park in tight corridors. Back out early when a path looks blocked.
- Cross the lake fast. Piranhas react from far away, so take the straightest line to the far shore.
- Use the break after a fall. Animals leave you alone for a few seconds after you stand up, so push through crowded spots then.
Lost City of S questions
Can you lose?
No. Running out of energy only knocks the explorer down for a moment. You get up where you fell and keep going.
Is the map random?
No. The layout is built from a fixed seed, so it is the same each time you play. That makes it easier to learn a good route through the maze.
How do I move on a phone?
Press anywhere on the screen and slide your finger. A floating stick appears where you touched, and the explorer walks the way you drag.
