Connect the Numbers

Connect eight numbered points in order, inspect every segment, and complete a reproducible browser puzzle for exactly 1,000.

How to use

  1. 1.Start from the automatically anchored point 1, then choose 2 through 8 in strict numeric order with the point buttons or keyboard.
  2. 2.Watch the Canvas path and ledger after every accepted segment. An out-of-order or nonadjacent crossing attempt is rejected and the exact same error is deduplicated.
  3. 3.Finish all seven clear segments for exactly 1,000 points, or use New layout before playing to select another seeded, in-bounds local arrangement.

About Connect the Numbers

Connect the Numbers is an original local dot-to-dot puzzle with eight numbered points. The starting board is fixed so its geometry and winning route can be reproduced exactly. A New layout control selects another safe authored arrangement through a deterministic seeded generator, making fresh placements available without hiding the active layout identity. No map, copyrighted picture, remote puzzle feed, upload, or external dataset is used.

Point 1 is connected automatically at the start. Your task is to choose 2, then 3, and continue through 8. Every accepted step adds the next segment to a real Canvas drawing while accessible HTML buttons remain aligned above the board for pointer, touch, and keyboard input. The interface displays the next required number, current score, mistakes, layout identifier, connection ledger, and feedback.

The geometry validator uses orientation signs plus on-segment bounds. It distinguishes a proper crossing, endpoint contact, and collinear overlap. A proposed segment is compared with earlier nonadjacent path segments. The immediately previous segment naturally shares its starting endpoint with the new segment, so that permitted path joint is excluded from the collision audit. Any other crossing or overlap is a rejected move.

Choosing the correct next point on a clear route advances the path. Seven accepted segments connect 1 through 8. The first six connections award 125 points each, and the completed seventh connection moves the score from 750 to exactly 1,000. The score describes completion of this authored board only; it is not a standardized spatial, motor, educational, or cognitive result.

Choosing a number out of sequence or proposing a crossing segment creates a recoverable mistake. The signature includes the active layout, expected number, chosen number, and collision result. Repeating the identical invalid attempt is deduplicated and cannot consume the second chance. A second distinct invalid attempt closes the run. Selecting an already connected point, an unknown point, or an invalid internal action is an atomic no-op.

Use the large numbered point controls with a mouse or touch screen. Keyboard players can tab to a point and press Enter or Space, or use the disclosed number keys 2 through 8 for the fixed route. New layout is an explicit user action; randomness never runs during React rendering. The chosen seed is passed into a pure layout function, so the same seed always produces the same unique in-bounds coordinates and remains testable.

Restart restores point 1, the initial fixed layout, zero score, and zero mistakes. Completion and deadlock freeze path actions and layout replacement, preserving the audited terminal result. The shared Boss Key remains available in the standard game shell. All processing and Canvas drawing stay in the browser, with no account, API, analytics-driven opponent, or new dependency.

Independent tests own a separate literal coordinate table and a separate segment-intersection oracle. They verify proper crossings, endpoint touches, collinear overlaps, separated lines, the allowed adjacent joint, and an injected crossing fixture. They replay 2 through 8 for the exact 1,000-point outcome, reach a two-distinct-error deadlock, check duplicate rejection behavior, and confirm terminal freezing. Additional seed cases prove deterministic output, coordinate uniqueness, board bounds, and a completable ordered route.

The board is intentionally small and transparent. A fresh layout changes geometry, not rules or scoring. Because every route and candidate set is authored for this product, the game makes no claim about real-world navigation, technical drafting, developmental milestones, or aptitude. Use the fixed opening when you want a fully reproducible golden path, or request a new layout for another local arrangement.

Methodology & sources

Represent eight original in-bounds point coordinates and anchor point 1. Accept only the disclosed next number, draw each accepted segment on Canvas, and reject a proposed segment when an independent nonadjacent path segment has a proper crossing, nonpermitted endpoint touch, or collinear overlap. Award six 125-point connections and a final 250-point completion including the seventh segment for exactly 1,000. Use a pure seeded candidate-layout selector only after an explicit user action; require coordinate uniqueness, bounds, deterministic replay, and route validity. Deduplicate an invalid-attempt signature, deadlock on the second distinct error, and freeze terminal states. Verify with a separate literal coordinate and intersection oracle.

Frequently asked questions

Are the point positions random?
The opening layout is fixed for reproducible verification. New layout explicitly chooses another deterministic seeded arrangement; randomness never runs silently during render.
How are crossing lines detected?
The local geometry check uses orientation and on-segment bounds for proper crossings, endpoint contacts, and collinear overlap, while allowing only the normal joint with the immediately previous segment.
How do I reach exactly 1,000 points?
Connect 2, 3, 4, 5, 6, 7, and 8 in order on a clear layout. The disclosed seven segment awards sum to exactly 1,000.
