Hand-building line puzzles and pipe levels, then praying they only have one answer?
Generate them instead — and know it, board after board.
Simple Connect is two puzzle engines in one toolkit, with three ways to play. It builds the boards, proves each one is uniquely solvable, and hands them to you as ready-to-use assets. You bring the movement, input, and art — it handles the puzzles.
THREE WAYS TO PLAY
- CONNECT — draw lines linking every pair of matching endpoints, no crossings. Fill-the-board or strict clean-lines rules. Square and hex grids.
- PIPES — the same pair boards as scrambled pipe tiles: every rotation is randomized, the player spins them back until each pipe reconnects.
- NETWORK — one connected system of straights, corners, T-junctions and crosses; rotate every tile until the whole thing links up with no leaks.
FOUNTAINS — DESIGN AROUND LANDMARKS
The network engine's signature trick.
- Pin any cell to demand an EXACT number of pipes feeding it — 2, 3, or 4.
- Click cells in the editor to author them, set a "?" pin to let the generator roll the count per board, or scatter random ones with a single slider.
- The generator satisfies every pin during construction and verifies the result — a pinned cell is never faked or approximated.
- Perfect for landmark-driven levels: the reservoir that needs four feeds, the boiler that takes three, the valve that must sit mid-line.
SHAPE THE NETWORK
- Branchiness: long winding corridors, or bushy junction-heavy sprawl.
- Junction bias: crank the density of Ts and crosses to the structural maximum.
- Loops: weld in redundant routes for closed circuits.
- Dead-end cap: seal the loose ends — all the way to ZERO for fully closed plumbing where every pipe connects at both ends.
VERIFIED UNIQUE
The part most generators skip.
- Plenty of tools make a board that's solvable. Few prove it has only one solution.
- Simple Connect checks every board and tells you straight: one solution or many.
- The rotation solver is validated against a brute-force oracle — the verdict is honest even on looped boards.
- It always finishes — built-in limits mean a check can never freeze your editor.
SQUARE AND HEX
- Pair puzzles come in both grid shapes from the same generator: square (four directions) and hexagonal (six directions).
- Flip one toggle and everything adapts — generator, checker, and rules.
GENERATE YOUR WAY
- Two no-code windows: set up, hit Generate, preview, keep the boards you like.
- Single puzzles or full packs, stored as assets you drag straight into a scene.
- Reproduce any board from a short seed — share the seed, not the data.
- Or generate at runtime from code, sync or async with progress — perfect for endless and daily modes.
PLAY IT RIGHT AWAY
- A complete, ready-to-play demo scene with all three modes behind one menu.
- Drag-to-draw play for Connect; tap-to-rotate boards with real pipe meshes (straights, corners, Ts, crosses, wall caps) for the rotate modes.
- Curated packs or random generation behind a progress bar, win flow, synthesized sound, and a built-in auto-solver.
- Drop in your own tile and pipe art, or run it with the included meshes.
DROP IT INTO YOUR GAME
- The puzzle engines have no dependencies and work in any project.
- A clean rules layer tells you which moves are legal and when a board is solved — wire your own controls in minutes.
- Pair data carries an integer Id only — no colors baked in. Drive links, wires, pipes, or numbers from the same puzzle.
