Bottle Circuit: Moonwater Lab

Bottle Circuit: a glass-routing puzzle in the Moonwater Lab

Rotate glass bottles to carry glowing moonwater across a five-by-five workbench. Bottle Circuit has twelve chambers, each with a marked inlet, a receiver and three lettered seals to collect along one connected route. Straight bottles and bent bottles carry water through two ports. Cork obstacles block a tile, while later chambers include fixed bottles that provide a clue you cannot rotate.

How to connect the bottles

Click or tap a bottle to rotate it one quarter-turn clockwise. Water updates after each turn, lighting the part of your route that connects to the inlet. A neighbor must have an opening toward the bottle sending water into it. Two bottles can look close without sharing the touching ports needed for a connection.

On a keyboard, use Tab to reach a bottle or the arrow keys to move focus around the grid. Enter or Space rotates the focused bottle. Each button names its row, column, shape and openings for assistive technology. Lettered seals provide a second way to follow progress beyond the water color.

Three seals and one receiver

Carry the water through A, B and C before finishing at the marked receiver on the right. You can visit the seals in any order. A matching section that remains disconnected from the inlet does not collect its seal, and sending water through another outside edge does not count as reaching the receiver. Spare bottles do not need to glow once the required route works.

A quiet puzzle with room to experiment

There is no timer or limited water supply. Undo reverses the last bottle action and restores its previous turn count. Reset returns the chamber to its starting layout. Align one bottle gives a hint by rotating one bottle on the supplied reference route into place. Hints remain counted after Undo; Reset starts a fresh attempt with no recorded hints.

The first three chambers introduce the routing idea without fixed bottles. Later workbenches place fixed glass along the intended route, and longer paths ask you to connect seals across more of the board. Completing a chamber unlocks the next. Use the chamber selector to return to an unlocked experiment and try another route.

Turns, reference counts and stars

REF shows the clockwise turn allowance for the supplied reference route from the starting arrangement. It is not a claim that no shorter solution exists. Finish without hints in REF plus two turns or fewer for three stars. Two stars allow up to two hints and REF plus eight turns; another completed route earns one star. Twelve chambers offer 36 stars in total.

Your browser saves unlocked chambers, the highest star result for each chamber and its smallest completed turn count when local storage is available. Returning opens your latest unlocked chamber with its starting board; unfinished rotations do not persist across a reload.

Learn a technique, then try it on the workbench

Use the first broken connection method to diagnose a dry route, plan a path through all three seals, or study turn counts and efficient replays. The guides explain separate parts of the puzzle rather than repeating the play page.
