Quiet Circuits vs Northdown

Quiet Circuits is a calm logic puzzle. Connect the dots. The board holds pairs of coloured endpoints; draw a path from each dot to its partner so the paths never cross and together fill every square. When the grid is full and every pair is joined, the board is solved. There is always one logical solution, and you never have to guess. Drag from a dot to trace its path, change your mind as often as you like, and follow the deductions until the whole grid is woven together. A ladder of five difficulties — Easy, Medium, Hard, Expert, and Master — on boards that grow with the challenge, from a gentle 5×5 to a tall 10×16 that fills the screen. Play the Daily puzzle — one shared board each day, the same for everyone — or roll unlimited boards in Practice and pick your own difficulty. Fifteen languages. Six themes, led by Circuit — a 3D circuit-board that tilts to catch the light as you move your phone — plus Light, Dark, Paper, Dusk, and a colour-blind-friendly Accessible palette with a clear symbol on every endpoint, so the paths stay readable for every kind of vision. Soft ambient music and gentle haptics, each with a one-tap mute right on the Home screen — no settings dive needed. An optional daily reminder nudges you back at the time you choose. No ads. No accounts. Only anonymous usage data, never personal information — your progress and stats live on this device.

Northdown is a 3D gravity puzzle. Your character cannot climb — so you tip the whole world instead. Swipe, the world rotates, the blocks tumble, and a wall becomes a floor. 100 hand-built levels. Free, offline, no wifi needed. A GRAVITY PUZZLE GAME WHERE THE WORLD MOVES, NOT YOU Gravity is the move. Rotate the world 90° and every block falls somewhere new — including you. Each level is a small floating world with exactly one way out, and finding it feels like a trick you taught yourself. If you have played a gravity puzzle before, you have not played one that turns the whole map. 100 LEVELS ACROSS 21 PAINTED PLACES Balloon skies, waterfall islands, a red canyon, temples in the clouds, the aurora, deep space, and lava spires at the very end. The sky changes every fifth level, and the light on the blocks follows it. A 3D GRAVITY MAZE IN YOUR POCKET Every stage is a small 3D maze built out of gravity blocks. Walk, tip, watch it fall, walk again. Simple to pick up, and the later levels are a genuine brain teaser. STARS, NOT TIMERS Every level has a shortest route. Match it for three stars. Nothing counts down, nothing runs out, nothing blocks you from playing. A relaxing puzzle game you can put down and pick straight back up. A NEW PUZZLE EVERY DAY The daily puzzle is the same one for everybody in the world. Build a streak — one free streak freeze a week forgives a missed day. SIX CHARACTERS TO EARN Sprocket the field medic, Rajan, Kofi, Zahra, Wisp and Bolt. Each has their own walk, their own voice and their own way of celebrating. Unlocked by playing, never by paying. PLAYS OFFLINE, ANYWHERE No account, no sign-in, no internet. An offline puzzle game for flights, commutes and dead zones. BUILT FOR ONE HAND Two on-screen pads: left walks, right tips the world. Portrait only, one thumb, any time. ACCESSIBLE Reduce-motion and colour-blind modes are built in. Coins are earned by playing and spent on hints, an extra undo, or a skip when you are truly stuck. Optional ads pay coins, and a one-time purchase removes the ads between levels forever. If you like gravity puzzles, isometric puzzle games, 3D logic games and brain teasers, Northdown was built for you.
