SOS: Night of the Titanic
April 14, 1912, 11:40 p.m. You are the wireless man on the largest ship in the world, and the set in front of you is suddenly the only thing between 2,200 people and the North Atlantic. This game puts you at that key. Five moments from the real night — from the ice warnings to the last signal — each with its message shown in dots and dashes: hear the correct rhythm, then send it yourself on a virtual straight key, graded element by element.
Ice in the wireless log
The Marconi room on the Boat Deck is busy: two operators, one 5 kW spark set, a queue of passenger telegrams for New York. All evening, ships up the lane have been reporting ice. Pass the word on down the wire — send the night's warning: ICE.

The history you are re-sending
Titanic's radio callsign was MGY, worked by two Marconi Company men: Jack Phillips, 25, senior operator, and Harold Bride, 21. Through the evening of April 14 the room earned its bread relaying passenger telegrams to Cape Race, Newfoundland, while neighboring ships — Mesaba among them — pushed ice warnings down the lane. At 23:40 the ship met the berg; within minutes Phillips was at the key.
The distress call of 1912 was CQD — "all stations: distress," in Marconi's house style. The newer international signal, SOS, had been standard since 1908 but was still strange to most ears; that night, on Bride's suggestion, the two men sent both, taking turns at the key. It was the distress call heard around the world — and the one that made SOS famous. The liner Carpathia (callsign MPA, Captain Rostron) answered and drove 58 miles through the same ice field at 17 knots to lift 705 survivors from the boats. Phillips stayed at the key until the power failed and did not survive; Bride did, carried off on a lifeboat with crushed feet and the story.
The direct consequence was the 1914 SOLAS convention: a radio watch kept around the clock on every ship at sea, and a permanent place in the law for the operator you just played.
What the game trains
- Element length under pressure. The 1:3 dot-dash ratio is what makes code readable — and the first thing adrenaline destroys. Chasing 100% forces honest timing.
- Rhythm copying. Each message is learned by hearing it first, the same listen-then-send loop operators have used since the 1900s.
- Prosigns. SOS as one fused nine-element symbol — why distress signals are designed as rhythms, not letters.
- The short classics. CQ, 73, OK — the abbreviations that made efficient CW conversation possible, learned as muscle memory instead of a table.

Frequently asked questions
Is this the real story of Titanic's wireless?
The skeleton is history: the Marconi room, operators Jack Phillips and Harold Bride, the callsign MGY, the ice warnings, CQD giving way to SOS (Bride's line "Send SOS; it may be your last chance to send it" is documented), Carpathia racing 58 miles to rescue 705 people, and Phillips not surviving. Timings are compressed and the messages you key are shortened to playable length — the real traffic ran for hours.
Do I need to know morse code to play?
No. Each message shows its dot-dash pattern as beads, and a button plays the correct rhythm before you send. You can play entirely by echo — listen, then copy the rhythm. If you want the letters to mean something, learn the sounds first with the Koch ladder and come back.
How is my sending scored?
Every press you make is timed and judged a dot or a dash, then compared position by position against the correct message. Green beads are correct elements, red are wrong; your score for each message is the percentage of elements that landed.
Why was SOS sent as one symbol?
The distress signal is a prosign — nine elements with no letter gaps, ...---..., run together so it cuts through noise as a single unmistakable rhythm. Spelled out as S O S with normal gaps it is much weaker on a bad circuit.
