Colorful World: Color Fill

Every colour has one starting dot. Draw a line out of it and cover every square on the board. Cross a line that is already there and it gives way — cut clean off at the crossing, back to its own dot. That is the whole game — and it gets harder for two hundred levels. TRAVEL THE WORLD Start at the Pyramids of Giza and work your way out: 200 levels across 40 places, 19 countries and 4 continents. Every place has its own photograph, from the Masai Mara to Machu Picchu to the dunes of Erg Chebbi — and every country its own music, an accordion waltz in France, Spanish guitar in Spain, Andean flutes in Peru. Finish a country and the next one opens. EVERY LEVEL HAS EXACTLY ONE ANSWER No luck, no dead ends, nothing generated and left unchecked. Every board is proved to have a single solution before it ships, so a level is always fair — and if you are stuck, it is because there is something to see. A REAL RAMP Eight difficulty tiers, from boards that teach you the rules up to Expert boards that make you route around your own lines. Stuck? Undo takes the whole board back as it was dealt, tap a colour's starting dot to clear just that line, or spend a hint that solves from where you actually are. A DIFFERENT CHALLENGE EVERY DAY One board a day, drawn from the hardest tiers in the game, under a rule that rotates: no hints, one shot where the undo button is gone, flawless where redrawing a line ends the run, beat the clock, or simply the biggest board there is. Everyone gets the same board under the same rule, and clearing it pays 200 coins. A LEADERBOARD AND A PROFILE Points from every clear rank you against everyone else playing. Your profile holds the portrait you pick, the name you choose and the rank you have earned. COME BACK TOMORROW A 7-day check-in that forgives a missed day, worth up to 200 coins. PLAYS ANYWHERE No ads. No in-app purchases. No account. Every level plays offline — only the leaderboard needs a connection, and the game says so instead of pretending.
