Yes. Like every FreeBTC game it costs nothing to play and you never stake anything. Good results add season points, and season leaders share sats from pots funded by the site’s ad revenue.

How accurate are the dates?

Every event in the bank has an exact, well-documented date. If we were not sure of a date, the event was left out.

Why are some events never together?

Events that give each other away, like two halvings or an ETF filing and its approval, never appear on the same day, and any two events are at least six months apart.

Only to break ties. Taking a minute to think is fine; solving in fewer tries matters much more.

Bitcoin Timeline Game — Put Bitcoin History in Order

How to play

Order the five events from oldest (top) to newest (bottom). Use the arrows, tap two events to swap them, or use Alt + ↑/↓ on a keyboard.
Press “Check order”. Orange squares are events in the right place; grey ones are not. The events’ dates stay hidden until the end.
You have three tries, and you cannot submit the same order twice.
Leaderboard score: solved on try 1 = 35, try 2 = 25, try 3 = 15. If you do not solve it, your score is the number of events in the right place on your last try (0–3). Ties are broken by time: faster wins.
Season points: solved on try 1 = 3 points, try 2 = 2 points, try 3 = 1 point. Solving it first time also earns the Timeline perfect badge.
One attempt per day. The puzzle is the same for everyone and changes at 00:00 UTC.

About this game

Each day Timeline picks five moments from Bitcoin’s history: the white paper, Pizza Day, the halvings, Mt. Gox, SegWit, El Salvador, the spot ETFs and many more. At least six months separate any two of them, so with a bit of knowledge every puzzle is solvable.

Put them in order and check. Positions you got right light up orange, like Wordle, and you have three tries. At the end you see every date on a timeline, with a line of context for each event.
