Mochi Color

Paint a candy map with just four colors so that no two regions touching along a border ever share the same paint.

About Mochi Color

Mochi Color is the classic four-color map puzzle dressed up as candy. Each level is a small grid quietly carved into contiguous blobs — the regions — and your one job is to paint every region so that no two regions sharing a border wear the same color. The whole game runs on a single gesture: tap a region and it cycles through the four paints. There is no color picker and no dragging — just tap, and tap again to change your mind.

The four paints are fixed across every level and every world: pink, gold, mint, and blue, in that order. A region starts blank, the first tap makes it pink, the next gold, then mint, then blue, and a fifth tap clears it back to blank so you can try again. That wrap-around is the heart of the puzzle. With only four crayons in the box you cannot just give every region its own color; you have to reuse them cleverly around the map.

Because every board is a flat grid map, the famous four-color theorem promises that four paints are always enough — and Mochi Color does not take that on faith. Before a level is ever shown to you the game builds the region adjacency graph and runs a backtracking solver to PROVE a clean four-coloring exists; any layout that fails is thrown out and a new one is generated. So the board always arrives completely blank and always has at least one tidy solution. You are building the answer from scratch, never untangling a half-finished mess and never handed an impossible map.

When two bordering regions end up the same color they both flash a pulsing red outline, so a clash is impossible to miss and there is no hidden mistake to hunt for. There is no timer, no move limit, and no way to lose — you simply keep tapping until every region is filled and every red outline is gone. The moment the map is clean a five-note arpeggio plays, a bright shimmer sweeps across the board, sparkles burst from each region, and you collect all three stars. It is a calm, tidy little logic game you can pick at for one puzzle or settle into for a long quiet streak.

There are twenty hand-built levels split into five candy worlds — Berry, Citrus, Mint, Ocean, and Galaxy, four levels each — and the difficulty grows by giving you a bigger grid and more regions to juggle: the opening Berry board is five regions on a tiny three-by-three grid, while the final Galaxy board packs twenty-two regions onto an eight-by-nine grid. Clear all twenty and an endless mode keeps generating fresh maps that ramp even further, so the supply of puzzles never runs out.

How to play Mochi Color

Tap any region to paint it. The first tap turns it pink, then gold, then mint, then blue; a fifth tap clears it back to blank.
Aim to give every region a color — the empty milky-white blobs are the regions still waiting to be painted.
Keep an eye on borders: two regions that share an edge must not end up the same color.
If two neighbors clash, both light up with a pulsing red outline. Tap one of them to cycle it to a different paint and the red goes away.
When every region is painted and no outlines are glowing red, the map is solved — you earn three stars with a chime and a shimmer.
Press Next to move on, or open the menu to jump to any unlocked level or into endless mode.

Tips & strategy

Begin with the most crowded region — the one touching the most neighbors. Pinning down its color first leaves you fewer ways to go wrong around it.
Corners only do not count. Two regions that meet at a single point are not neighbors here; only regions sharing an actual edge can clash, so do not waste a paint avoiding a diagonal touch.
Think in pairs and chains, not in choices. With four paints, a clash is almost always fixed by re-cycling one neighbor rather than wrestling with the region itself.
There is no penalty for a red outline and no way to fail, so experiment freely. The red glow is a helper, not a warning — keep cycling clashing regions and the map untangles itself.
If a knot of regions all fight each other, hit R to clear the whole board and recolor that cluster as a fresh group instead of patching one region at a time.
On the bigger Ocean and Galaxy maps, work outward from one corner so the regions you have already settled stay locked in as fixed neighbors while you paint forward.
Stuck and idle for a few seconds? A cartoon finger appears and taps over a good region to try next — let it nudge you toward the most useful move.

Game features

A true four-color map puzzle built on the four-color theorem: only pink, gold, mint, and blue, reused so no two bordering regions match.
One-gesture play: every region is colored by tapping to cycle through the four paints and a blank state — no palette to pick from, no dragging.
Twenty hand-built levels across five candy worlds — Berry, Citrus, Mint, Ocean, and Galaxy — scaling from five regions on a 3x3 grid up to twenty-two regions on an 8x9 grid.
Endless mode that generates fresh maps once the curated worlds are cleared, growing the grid and region count as the level number climbs so it never settles into easy.
Every board is verified solvable by a backtracking four-coloring solver before it appears, and always starts completely blank — never pre-filled, never impossible.
Live clash feedback: any two same-colored neighbors flash a pulsing red outline, so there is no hidden mistake and no guesswork about what to fix.
Relaxed by design — no timer, no move limit, and no fail state; you can always wipe the map with R and start the coloring fresh.
A four-note paint chime (a different pitch for each color) plus a sparkly win arpeggio, with one tap to mute, and a level-select grid that remembers your unlocked levels and stars.

Frequently asked questions

What exactly is the four-color rule in Mochi Color?

Every region on the map must be painted, and no two regions that share a border may use the same color. You have exactly four paints — pink, gold, mint, and blue — and the puzzle is figuring out how to reuse them so that touching regions always differ.

Can I really solve every level with only four colors?

Yes, every time. The boards are flat grid maps, and the four-color theorem proves four colors are always enough. Mochi Color goes further: it runs a solver to confirm a valid four-coloring exists for each board before showing it to you, and discards any layout that cannot be solved, so you are never handed an impossible map.

How do I change a region's color if I picked wrong?

Just tap the same region again. Each tap moves it to the next paint — pink, gold, mint, blue — and one more tap clears it back to blank. To wipe the entire map and restart the coloring, press R or Backspace, or use Clear all colors in settings.

Do regions that only touch at a corner count as neighbors?

No. Only regions that share an actual edge are considered touching. Two regions that meet at a single corner point are allowed to be the same color, so you never need to spend a paint avoiding a diagonal touch.

What does the pulsing red outline mean?

It marks a clash: two bordering regions currently share the same color. Both regions glow red so you can spot the problem instantly. There is no penalty for it — recolor either one of the pair and the outline disappears.

How many levels are there, and what is endless mode?

There are twenty curated levels across five worlds, from a 5-region opener up to a 22-region finale. After those, endless mode keeps generating new maps that ramp the grid size and region count higher than the curated set, so the puzzles never run out.

Is there a way to lose, or a clock running?

No. Mochi Color has no timer, no move counter, and no fail state. Completing any level always awards all three stars, and the only goal is a fully painted board with no clashes — take as long as you like.
