Colors by Number ®: No.Draw

Review by eFreeware

The pitch behind Colors by Number is simple enough to explain in one line: every pixel block on the canvas carries a number, and you fill it with the matching color until a picture appears. That is the whole game, and it is the reason the app has built a following of over 50 million installs with a 4.6 average across 370,350 ratings. There is no drawing skill required and no blank page to stare at.

That makes it a natural fit for people who want something creative to do with their hands without committing to a project. If you like the idea of coloring but dislike choosing colors or staying inside lines, the numbered grid does that work for you. It also suits anyone looking for a quiet few minutes on a phone rather than a challenge to beat.

A coloring book that draws the outlines for you

Most coloring apps ask you to make decisions. This one removes them. You tap a block, the color is already decided by the number inside it, and the only judgment left is which block to do next. The developer calls it the most popular free color-by-number game, and while that kind of claim is hard to verify, the install numbers suggest the format has found a wide audience.

The appeal for me is that it turns a creative hobby into something closer to a puzzle. You can see the shape emerging as you fill sections in, which gives a small sense of progress with each block. It is a different pleasure from drawing freely, but it is one that works well on a small screen where precision is awkward.

The developer also frames the game as practice for drawing and coloring skills, and as a way to relax. Both are reasonable descriptions of what filling numbered blocks does: you build familiarity with how colors sit next to each other, and the repetition is calming rather than demanding.

Numbered blocks and a growing pile of pictures

The core loop is as basic as it sounds. Each picture is a grid of small blocks, every block has a number, and the numbers correspond to colors in a palette. You work through them until the image is complete. The developer describes the gameplay as super easy, and that is accurate: there is nothing to learn beyond matching a number to a color.

What keeps it from being a one-off is the volume of material. There are tons of pixel artworks available, with more added daily, so the catalog keeps growing rather than running dry after a few sessions. For anyone who finishes pictures quickly, that steady supply is the main reason to stay with it.

The March 2026 update added more free materials, new themes and improved daily login rewards. Themes matter more than they might sound, since a coloring game lives or dies on whether the pictures interest you, and a wider spread of styles gives you more reason to open it again.

Built for short, unhurried sessions

Nothing here pushes you toward speed. You can fill a handful of blocks while waiting for a kettle to boil, or settle in for a longer stretch and finish a whole picture. Because each block is a discrete tap, the game tolerates interruption well: you can put it down mid-picture and pick it up later without losing your place in any meaningful sense.

That flexibility is what makes the format work for such a broad age range. It is pitched as suitable for any age, and the Everyone rating fits that. A child can manage the number matching, and an adult can treat the same activity as a way to switch off.

The experience is described as color therapy and stress relief. I would treat that as the intended mood rather than a clinical promise, but the design does support it: no timers, no failure states, and a steady visual reward as the picture fills in.

Where the free model shows up

Colors by Number is free to download and supported by ads, and it also offers in-app purchases. I would go in expecting the usual arrangement for a free coloring game rather than assuming everything is unlocked from the start.

The experience comes with commercial interruptions and optional spending, so anyone who prefers a completely quiet, ad-free session should weigh that before installing. The daily login rewards are a separate incentive.

None of this is unusual for the category, and the install and rating figures suggest a large number of people find the trade acceptable. It is worth being clear about it up front, though, because the calm tone of the game sits a little awkwardly next to ads and purchase prompts.

Who gets the most from it

This is a good fit for someone who wants a creative pastime that asks nothing of them beyond attention. If you enjoy jigsaw puzzles, paint-by-numbers kits or similar guided activities, the same satisfaction is here in a form you can carry in a pocket. It is also a reasonable choice for older children and teenagers who like pixel art and want something gentler than a competitive game.

It is less suited to anyone looking for a drawing tool. The pattern is the point. If you want to make your own pictures, this is the wrong shape of app; if you want to fill in someone else's, it is exactly right.

The low demands also make it a decent option for people who find most mobile games stressful. You color, the picture grows, and you stop when you like.

A calm pick for anyone who likes guided coloring

Colors by Number does one thing and does it without complication. The numbered-block system is easy to understand, the catalog is large and refreshed regularly, and the whole experience is built around relaxation rather than challenge. The 4.6 average from a very large number of ratings suggests that approach lands with most people who try it.

The caveats are the free-model ones: ads, in-app purchases and a daily-reward loop nudging you to return. If you can live with those, the coloring itself is a pleasant, undemanding way to spend a few minutes. If commercial interruptions would spoil the mood, that is the main thing to consider before downloading.

I would point this at anyone who wants a guided creative activity with no learning curve, particularly those who already enjoy pixel art or paint-by-number formats. It has been on Google Play since November 2017 and was still being updated in March 2026, which is a long run for a game this simple.
