Progression
1000 levels, 7 shapes
No level was placed by hand. Each one is generated from its own number, which means the difficulty curve is a formula you can read rather than a designer's guess.
Arrows equal the level number
Level 1 has one arrow. Level 40 has forty. Level 1000 has a thousand. There is no other difficulty dial for board density, which makes the ramp completely predictable: every level you clear adds exactly one arrow.
The board grows to accommodate them, so cells get smaller as you climb. Around the mid-hundreds the board becomes genuinely dense, and pointer accuracy starts to matter more than reasoning. Keyboard selection sidesteps that entirely; see the accessibility statement for where the practical limits sit.
Determinism
Boards are produced by a seeded generator, and the seed is derived from the level number. Same number, same board, on every device, for every player, every time. Nothing is downloaded and nothing is stored, which is also why the extension needs no network access.
A practical upside: if you get stuck on level 317, so is everybody else, on the identical board.
The seven silhouettes
Arrows are packed inside a mask rather than scattered. The shape for any level
is (level − 1) mod 7, so the sequence
repeats every 7 levels with one more arrow each time
round.

Where each mechanic switches on
Nothing appears gradually or at random. Each of these has an exact threshold.
| From level | What changes |
|---|---|
| 1 | One arrow, one tap. Arrows bend at most once up to level 5. |
| 6 | Arrows may bend twice, so paths start to interleave. |
| 11 | Dependency locks. An arrow can be padlocked until a specific other arrow leaves. Order of play now matters. |
| 16 | Up to three bends per arrow. |
| 21 | Timed blockers. Cells alternate between solid and passable on a fixed cycle. Waiting becomes a legitimate move. |
| 30 | An extra percussion layer joins the soundtrack. Cosmetic, but you will notice it. |
| 36 | Up to four bends, and lock frequency keeps climbing with level. |
| 71 | Up to five bends, the maximum. Paths are now heavily folded. |
| 36 onward | An additional blocker appears roughly every 15 levels, up to six on a board. |
| 1000 | The final board: a thousand arrows inside a single silhouette. |
Scoring
100 points per arrow cleared, multiplied by your combo streak up to 5x. 500 for finishing a level, and a further 250 every tenth level, which also earns some confetti. Score is a record of how you played, not a gate on anything.
Unlocking
Levels unlock in order: finish one to reach the next. You can revisit any level you have already unlocked from the picker beside the board, so there is no penalty for going back to a board you enjoyed.
