Code Crossing is the classic color-code logic puzzle, rebuilt for a quiet daily ritual on iPhone and iPad. A hidden code of four colors waits behind the slots. You pick four colors and submit. The app responds with a row of feedback dots — a yellow dot for a color in the right spot, a green dot for a color in the wrong spot, nothing at all for a color that isn't in the code. From those dots, you deduce. The first guess is a shot in the dark. The second guess is sharper. The fifth guess, if you are reading the dots well, is often the win.
The Career trail is a neon-glowing path climbing through a deep-blue starfield from your first easy level all the way to the expert finale a hundred steps up. Early levels open with four colors and three slots and twelve attempts — gentle ground for learning the rhythm. The middle stretch settles into the classic six colors, four slots, ten attempts. The hard climb adds an eighth color. The final climb stretches to five slots. Every tenth level is a Boss level with a special twist: a code with two consecutive same-color slots, a time-limited window, a code that uses only three of the six colors, a level where hints are disabled. Each level scores you one, two, or three stars based on how quickly you cracked it.
Daily Challenge is a single global code shared by everyone, every day. Solve it and your result shares as an emoji grid for friends to compare. Endless Mode is exactly what it sounds like — random codes, one after another, a streak counter ticking up.
Stats shows your win rate, your average attempts, your longest streak, and a small heatmap that paints itself in as you play through the year. Hints sit in the corner — three a day, each one reveals one color or confirms one slot. Five color themes unlock as you climb the trail: arcade, neon, candy, deep sea, monochrome.
Code Crossing is built to be the cleanest color-code puzzle on the App Store. A deep-blue arcade palette, bold yellow and lime accents, big bright pegs that pop against the dark. Open the map and start the climb.
