Chroma: Four Colour Game
Map Colouring Logic Puzzle
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Two hundred hand-checked maps, a fresh puzzle every day, and no two neighbours ever the same colour. Can you solve every board with only three colours?
CHROMA
Colour the map so no two touching regions share a colour. It sounds simple, but every map is a fresh little logic puzzle, and the famous Four Colour Theorem promises that four colours are always enough.
Pick a colour, tap a region, and watch the map come together. Regions that share a border can never match, though touching at a single corner is fine, just like countries on a real map.
HOW TO PLAY
Tap a colour from the palette, then tap a region to fill it. Keep going until the whole map is coloured and no two neighbours clash. Stuck on a tricky corner? A hint fills one region for you, and if you finish a map using only three colours you earn a bonus.
200 MAPS
Two hundred hand-checked maps are split across four difficulty tiers, from gentle Easy boards up to dense Super Hard ones with dozens of regions. Every single map is guaranteed solvable. A new Daily Challenge arrives each day for a coin bonus and a streak to keep going.
RELAX OR RACE
Play untimed and take all the time you like, or switch on the clock for a bigger coin reward. Your best times and completions are saved.
COINS AND HINTS
Earn coins by finishing maps and daily challenges. Spend them on hints when you need a nudge, or watch a short advert instead. Once a day you can watch an advert for five free coins.
REMOVE ADVERTS
Prefer a clean run? The optional ad-free upgrade removes advert breaks between levels and still lets you watch reward adverts for hints if you want them. Choose a monthly option or a one-time forever unlock, and either way you collect five bonus coins every day.
