Changelog

Level multipliers now climb 1×, 3×, 10×, 40×, 150×, 500× — previously 1×, 2×, 4×, 10×. Base scores went up tenfold to match.

The old curve paid a long run about as well as a short one, so there was little reason to care whether a number was on its second level or its fifth. Multipliers now grow much faster than the hits they cost, which makes surviving worth disproportionately more than starting well.

Every number now levels on the same curve: level n costs n(n−1)/2 hits. The horn no longer climbs at twice the rate of the box numbers.

The horn keeps its advantage where it always belonged — its base score, which is five to ten times the core's. Two separate curves made that advantage hard to read and easy to double-count.

A hard way pays 3× on 4, 6, 8 and 10 only. A 2 or a 12 no longer pays a hard-way bonus.

A 2 is always two ones and a 12 is always two sixes, so they were collecting the bonus on every single hit. A multiplier nobody can fail to earn is not a multiplier — it is base score wearing a hat, and it was quietly worth about a sixth of every point scored in the game.

Numbers can now be working. The dealer's puck marks the point, and bringing a working number home pays double and is worth an extra point of XP.

The first three rolls are no longer risk-free. A seven can now end a run on roll one, at a thousand to one.

A guaranteed-safe opening made the first three rolls a formality. One in a thousand keeps a board practically always establishing while making "practically" do real work.

Badges. Some runs earn one; they appear on your profile and link back to the run that earned them.

Runs recorded before this change were removed from the leaderboard.

A board is replayed from its seeds rather than stored roll by roll, so a scoring change makes an older run replay to a different score than the one it was ranked on. Leaving them would have meant a leaderboard whose entries disagreed with their own replays — which is exactly the thing being provably fair is supposed to rule out. There were four, all recorded the same day they were removed.

Runs have their own addresses. A replay is a link you can send someone, and it opens on the finished board.

Pages are rendered on the server, and the rules are published in full on the "how it works" page.
