Servant of the Lake Stone Coin Puzzle Solution

How to solve the Servant of the Lake stone coin puzzle in the opening carriage scene — arrange the striped cups correctly and grab the coin for the driver.

Arrange the five striped tin cups on the carriage window ledge in order from fewest stripes to most (1 through 5). The cup with a single stripe pops open once the row is correct, and inside is the coin you need to pay the driver.

This is the very first real puzzle in Servant of the Lake, appearing in the opening carriage scene within the first few minutes of the game. It's a teaching puzzle — low difficulty, but it's also the single most-searched puzzle in the game simply because it's the first thing every new player runs into.

Where to find all five cups

Three cups are already sitting on the window ledge when the scene starts. The other two need to be found: one is near the carriage's open window, and the other is tucked inside a small compartment at the bottom of the carriage. Before you get to the cups, there's an easy-to-miss step at the flowerbed: grab the carrot sitting there first, since it's used later to feed the horse.

Check the flowerbed and pick up the carrot.
Open the small compartment at the bottom of the carriage to find the second hidden cup.
Check near the open carriage window for the third hidden cup.
Line up all five cups on the ledge by stripe count, ascending from 1 to 5.
Open the one-stripe cup and take the coin inside.

What the coin unlocks

Hand the coin to the driver as your fare. Once he leaves, he drops an iron rod on the ground — pick it up. That rod is what you'll use to pry open a loose floorboard next to the flowerbed, which is where the front-door key to the estate is hidden. This is the item chain that formally gets you into the main game, so don't skip past it even if the cup puzzle feels solved.

Multiple independent sources agree

Community walkthroughs and a direct video playthrough both confirm the cups sort strictly by stripe count, ascending. If your cups don't seem to line up, double check you've actually found all five — it's easy to leave the compartment cup behind.

A small worldbuilding detail

The crest carved into the carriage itself shows a tree, a black egg, an elixir bottle, and a crow together. Longtime Rusty Lake fans read this as a visual hint toward the elixir recipe that becomes central to the Day 3 story — it's not needed to solve this puzzle, but it's worth a second look if you're paying attention to the game's foreshadowing.
