The current eight-stage beta connects a coastal chart, a gear drive and a set of optical plates. The gear controls below let you choose a driver and a driven gear. The chart and lens stations supply the other records for your rescue report.

Split the chart and mechanical work, then check the optical plates together. Before the rescue report, explain how each result follows from its record. Neither player needs to hold a control while the other works.
Open a room for two →A SEPARATE PRACTICE PUZZLE · NO ROOM NEEDED
A separate training rig turns at 18 rpm. Its driver has 10 teeth and its driven gear has 30 teeth. Using output = input × driver teeth ÷ driven teeth, how fast does the output turn?
The larger driven gear makes the output slower. The training rig uses different numbers from the lighthouse apparatus; it does not give the game’s gear selection.
YOUR BRIEF
The storm has reduced the world outside to darkness and scattered reports. Your team takes over a lighthouse whose chart, drive and lens must agree before a useful signal can be sent. The ship needs a position it can trust, and you need evidence that the equipment is ready.
In the current beta, three workstations feed into a combined rescue report. Solve the chart, mechanical and optical problems, compare their results, then configure the signal and complete the coordinated release. The final sequence depends on the work your team has already done.
OBSERVE · COMPARE · EXPLAIN
Use the position reports to locate the ship on the grid and explain why the reports agree.
Compare driving and driven gears, then combine optical plates to make the required lens pattern.
Bring the verified workstation results into one report and set the final signal sequence together.
Share the chart, gear and lens investigations across the group, then reconvene before the final signal. Teammates can inspect unlocked stations separately, while answers and progress remain in one shared room.
Create one room, share its invitation code and let each friend join from a browser. The room supports up to ten members. On a small screen, use the image inspection controls to examine clues more closely.
A practical problem-solving adventure for families with older children and adult groups. It includes grid reasoning, gear ratios and pattern matching. Younger players may need help with English instructions and the calculations. There are storm and rescue themes, with no jump scares.
Age and difficulty are design guidance, not formal ratings. Optional hints help when your team gets stuck.

This film introduces the forthcoming 1953 story. It is not the storyline of the current playable beta above. The setting is the real North Sea flood; the harbour, characters, equipment, timings and rescue are fictional.
English synthetic narration and on-screen text. Chinese subtitles available. No autoplay. Download MP4
January, nineteen fifty-three. A North Sea storm closes around the coast. At a fictional harbour, the phones fail. Eight people wait offshore. You take the relief watch. The main light must stay on. Restore the harbour signal. Read the bearings. Find a usable approach. Every repair brings the launch one step closer to shore. The Last Lighthouse. Keep the light. Bring them home.
The Start button opens the original eight-stage lighthouse beta described on this page. The Last Watch is a new story edition being prepared for release; its film below is clearly marked as a preview.
Our design suggestion is 12+ with adult support. This is not a formal age rating. Consider English reading ability, comfort with storm and rescue themes, and confidence with the calculations.
Yes. Once the investigation stations are unlocked, players can explore different clues and compare their findings before completing the shared rescue report.
