Touch: Tap a star that touches one or more of its own colour to clear that whole constellation. Buttons along the bottom: Undo the last move, Redraw to reshuffle (limited), Pause, and Mute. · Keyboard: Arrow keys or WASD move the cursor between stars, Space or Enter clears the constellation under it, U undoes, R redraws, P or Esc pauses, M mutes. The mouse also works: click a constellation to clear it.
About:
A constellation-clearing sky-chart puzzle, made in-house for Leetdom in the spirit of the 2000s Flash group-removal classics. The night sky is a grid of coloured stars. Tap any star joined to one or more of its own colour and the whole connected constellation fades away. Stars above fall down to fill the gap, and when a column empties it slides west to close the hole, so every clear reshapes the chart. Bigger constellations are worth far more than small ones — a clear of n stars scores n times n-minus-one — so the game is about reading the board and merging small clusters into one huge chain before you commit. Clear the whole sky and you bank a full-sky bonus.
Each chart sets a target score. Some stars are anchors: they never fall and they split a column into separate stacks, so gravity and the westward drift bend around them. You get a small, limited pool of redraws that reshuffle the loose stars when you are stuck, and a single-step undo for the move you wish you hadn't made. There are 20 charts across four skies — Duskbank, The Weft, Deepnight and Starfall Gyre — growing from three colours and open boards to five colours threaded with anchors and just one redraw to spare. Every chart is generated from a fixed seed and validated by a solver before it ships, so each target is provably reachable. The five star colours each have their own glyph shape as well as hue, so the chart reads clearly without relying on colour alone. All of the art is drawn in canvas and all of the sound is synthesised in code — there are no image or audio files.

Phone check: 2026-10-03: the deterministic core has node unit tests (7253 checks) covering group-finding, gravity through anchor-split columns, westward column drift, redraw, scoring and full-clear detection, plus fuzzed invariants. All 20 charts are generated from fixed seeds and a playout solver proves every target is reachable (validation OK). In the browser, real CDP input on a portrait phone (390x844, dpr3), a landscape phone (844x390, dpr2) and a 1280x800 desktop: 25 checks, 0 failures — title, tap-to-play, clearing constellations through real taps to beat a chart goal, the clear screen and one-tap advance, stars persisted, next chart unlocked, pause on hidden tab and resume, resize to landscape, desktop mouse and keyboard, the chart-select map, and a full boot-and-play run with localStorage blocked. Zero console errors and no network requests (only the five same-origin files load). Audio measured from a 30s offline render: full-mix peak -12.3 dBFS, music sits 12.2 dB under SFX, true silence between sounds, no harsh highs and no single repeating drone — all gates pass. A solver-driven bot cleared chart 1 to full-sky; targets demand genuine planning and often a near-full clear.

Beetle ParadeA line of beetles is marching down a garden trail toward the burrow. Flick beetles into the line from your snail; three of a colour scuttle off, and the gaps snap shut into chain reactions.
Bloom FourDrop linked elemental seeds into a narrow garden, matching four or more of a kind to make them bloom. Blooms collapse the garden, chaining into fresh matches and burying your rival in thornpods. Duel a three-tier AI or climb an endless, quickening solo run.
Bug TrafficBees, bumblebees, dragonflies and ladybirds drift into the garden. Draw each one a path home to the flowers of its colour, and never let two of them bump.
Drip DropAim a brass watering spout, let a single dewdrop fall through a night greenhouse of glass buds, and open every orange bloom before your ten drops run out. Five gardeners, 34 boards, 16 challenges.
