Prismo Coloring

You start by choosing a picture. Each illustration begins with blank areas waiting for colour. The pictures are illustrations made for colouring, so the outlines are already drawn and your part is the colour.

Then you choose a palette and a brush with a mouse click, and paint by clicking and dragging over the picture. Filling the blank areas one by one turns the outline into a finished digital artwork. The palette you pick shapes the whole picture. A warm palette and a cool one can make the same illustration feel like two different works, so the choice is worth a moment before you start painting.

There is no timer or score in Poki's description; the game is meant to be played at your own pace. Poki files it under decorating games, with colouring and drawing as tags. That makes it one of the few games here that you cannot really do wrong: every choice of colour is valid, and a finished picture is simply a picture you like.

• Choose the palette before you start painting. Deciding the colours first keeps the finished picture consistent. A palette of a few related colours usually gives a calmer result than one with many strong contrasts.

• Fill the largest blank areas first, then the small details; it is easier to judge the colours once the big shapes are in. Small areas next to each other are easier to judge once their surroundings have colour.

• Try the same picture with a different palette. The change of mood can be surprising. It is a good way to see how much the palette choice alone changes a picture.

• Use it as a wind-down: one picture per sitting is a good rhythm.

Players of any age who like colouring books, and anyone who wants a calm break between busier games. It works well for younger players, since Poki mentions no score or timer, and for adults who use colouring to switch off after work. It pairs naturally with World of Yarn if you want something calm but with a bit more thinking.

  There is no challenge in the usual sense, so players looking for difficulty will not find it here. The appeal depends on enjoying colouring for its own sake.

  Painting by click and drag is precise with a mouse; on a small phone screen, detailed areas can be fiddly.
