## What is Chroma?

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.
