Matches:

Uncross Drag the glowing nodes until none of the wicks cross and the grid powers up. Then route a limited current from the generator to bloom as many beacons as the budget allows. Eighteen hand-tuned, always-solvable boards.

Tumble Block Roll a two-cell stone reliquary end over end across broken tile mechanisms and land it standing upright on the glyph. Twelve hand-built, solver-proven boards with switches, bridges and fragile tiles, unlimited undo and a one-tap reset.

Channel Rush A spring is about to pulse and the meadows are thirsty. Lay and rotate irrigation channels before the countdown runs out, then release the water and watch it race through your routes to feed every habitat without wasting a drop.

Wisp Link Each glowing marsh-wisp has a twin of the same colour. Trace a trail of light from one to the other, fill every tile, and never let two trails cross.

Crate Keeper A deep vault hums because its archive crates have drifted off their resonant floor seals. You are the keeper: walk into a crate to push it, one at a time, and slide every crate home to quiet the room. Undo and restart are always free, so the only thing you can lose is the wrong idea.

Canal Jam A crowded canal lock is jammed solid and the copper barge is boxed in. Every narrowboat only drifts the way it points, so you slide the others aside, clear a channel, and ease the copper barge out through the gate.

Picture Weave A picture-logic puzzler: read the number clues on every row and column to work out which tiles to weave, and a hidden glyph slowly appears. Unique solvable boards, a gentle Journey and an Endless streak, undo, notes, a contradiction check and colour-blind-safe marks.

Clockwork Vaults A little wind-up automaton creeps through twenty clockwork vaults one tile at a time. Gather every cog to open the socket gate, juggle keys, crates and special soles, dodge patrolling machines, and slip out through the hatch.

Wisp Echoes Pilot a wisp of light through a dark hall, then leave it behind as an echo that replays your path exactly. With a few recorded selves holding lanterns and parting veils at once, guide the last wisp to the hearth.

Cradlestone A carved idol is held aloft by a tower of runed stones. Dissolve them in the right order and the idol settles gently onto its cradle; pull the wrong one and it topples, drops too hard and shatters, or slides off into the dark.

Star Chart Restore a monastery's faded star-chart by setting glyphs so every row, every column and every 3x3 ward holds all nine marks exactly once. Four graded difficulties, a fresh daily chart, pencil marks, undo and a hint — made to be played equally well by thumb or by keyboard.

Lamp Code Read the lighthouse keeper's signal before the lamps go dark. Guess the five-letter word in six tries, with gold and amber lamp feedback that also speaks in shapes for colour-blind play. Then switch to Beacon and crack a four-lamp colour code instead.

0h h1 Fill the grid with red and blue: no three in a row, equal counts per line, no two lines alike.

0h n0 0h h1's companion: every blue number counts exactly the blue dots it can see.

CheaterMind A Mastermind variant where the computer never actually commits to a secret code until it has to — an adversarial twist confirmed working cleanly through a tap-native color-picker UI.

Daily Puzzle A new small logic puzzle every day, and a different kind of puzzle for each day of the week.

Picreact A React-built Nonogram/Picross. Tap a cell to cycle it through fill, cross, and clear.
