London, 1843. Ada Lovelace has just finished writing the world's first computer
program for Charles Babbage's mechanical calculator, the Analytical Engine. But Babbage
believes the machine is only fit for simple arithmetic. Ada knows it can do far more
— manipulate symbols, draw graphics, even compose music — and she must prove
it before the investors arrive and the funding is cut off.
Ada has locked her groundbreaking notes and the final code inside a prototype security
box in her study. She has left behind a trail of mathematical puzzles — built from
the very geometry of the Engine itself — so that only a true mathematician can
reach her work. Four clues guard four digits. Together they open the box.
Your mission: You are Ada's trusted assistants. Solve the four clue cards on the
table to collect the four code digits. You have exactly 8 minutes. When you have
all four digits, enter them into the security box below — before the investors
knock on the door.

Game Master Answer Key
Clue 1, Punched Card Coordinate: 2x − 3y = 3 and 4x + 3y = 15 give x = 3, y = 1; grid (col 3, row 1) = 7
Clue 2, Iron Triangle: 180 − (47 + 70) = 63°; units digit = 3
The box springs open. Inside lie Ada's notes and the final program — an algorithm
for computing the Bernoulli numbers, the world's first computer program. As the
investors fill the doorway, Ada feeds the punched card into the Engine. It clatters to
life, and the room falls silent. The machine is not merely a calculator; it is a loom
for ideas. Ada's place in history is secured — and it was geometry that unlocked it.
Did You Know?
The First Program: In 1843, Ada Lovelace published an algorithm for calculating Bernoulli numbers for Charles Babbage's Analytical Engine — widely considered the world's first computer program.
Poetical Science: Ada called her approach "poetical science," and predicted that computers would one day manipulate symbols, create graphics, and compose complex music — not just crunch numbers.
The Mechanical Loom: She saw that computing mirrored weaving, writing that the machine "weaves algebraic patterns just as the Jacquard loom weaves flowers and leaves."
A Poet's Daughter: Ada was the daughter of the famous poet Lord Byron, though she never knew him — her mother steered her toward mathematics, hoping to suppress any poetic inheritance.

Time Has Run Out
The study door swings open. The investors file in, pocket watches in hand, and Babbage's
funding is withdrawn before the Engine can prove itself. Ada's notes stay locked away
— for now. She leaves the puzzles standing for the next true mathematician to find.
