Under the hood
How the Rail Works
Every round starts with a stack of milestone cards: the heavy plough, gunpowder, the magnetic compass. You drag them between the gold Earliest marker and the gold Latest marker until the stack reads like a timeline. When you are happy, press Lock it in. Wrong cards slide to their real position in crimson, and correct ones glow gold.
The score rewards nearness. Put a card one slot off and you lose far less than if you bury it at the wrong end. Your Skill level, from 1 to 10, listens to how you play. At Skill 4 the next round spaces years about 129 apart. At Skill 3 it was about 216. Tap the reading-of-history card on the Play tab and Fidra shows how that number is chosen.
Everything runs on the phone. Today's six are chosen from the device's own calendar date, so nothing is fetched and no account is needed. That also means the daily set is the same for everyone who plays on the same date, and your breakdown stays on screen all day after your single attempt.

Inside the cabinet
Six Drawers of History to Open
Closeness scoring
A near miss still earns points. A perfect rail fills the score ring to 100 and shows "5 of 5 in the right place".
Adaptive Skill
Your level, 1 to 10, sets how far apart the card years sit, so rounds stay hard without turning cruel.
Pin the year
Open up to four clues, drag a year dial, and nudge by one year. The dial for the load-bearing arch covers 3700 BCE to 979.
Today's sequence
Six shared cards, one attempt per day, and a streak that counts the days you show up.
Mix in your own
Add "Moved to a new city" with a year, a one-line note and a picture. It joins the rounds beside quarantine and paper.
Century map
See how many milestones you have met in Ancient, Medieval, Early Modern, Industrial, Electric and Digital, with a bar for each era.
