In short: Eraly's own infinite mode sits behind a sign-in and a $5 payment (checked 24 Oct 2026). Yearline Unlimited above is a free alternative: endless 7-moment rounds, an optional era filter, and the same closer-is-better scoring. No account; your best round stays in this browser.

A 4-step routine for unlimited practice
- Play one round on All eras to see where you lose points — the gap bar after each moment shows how far off you were.
- Drill your worst era for three or four rounds. Learn two or three anchor years for it from the table above.
- Date by technology first. Steam, telegraph, radio, TV, internet: each one rules out whole centuries before you think about the exact year.
- Commit to a decade, then nudge. Use the ±10 and ±1 buttons to move from the decade you are sure of to the year you think is right.
