How To Play

Playing the Game

There are two level types: "Same Reference" and "No Reference." This refers to a reference image.

When using "Same Reference," you will see two copies of the same image. The left one is the reference image - it has not been altered by the game. The right image is "in play" - being altered by the game or by you. How it gets used depends on the round type (explained below), but you will always have a visual reference.

"No Reference" levels will show you a rectangle of neutral gray on the left, where the reference image would otherwise be. You must play these levels without the benefit of a reference image.

We highly recommend using "Same Reference" until you are getting consistently high scores on all difficulties.

There are five difficulties. Because there is an element of randomization, we recommend playing through each difficulty at least a few times before moving on. Without a large enough set of results, it may be difficult to gauge your progress or current skill level. All five difficulties are available for "Identification" and "Correction" rounds (described below). Whether you want to play all five difficulties on Identification, then all five difficulties on Correction, or whether you want to go back and forth between Identification and Correction as you increase the difficulty, is up to you.

• In an "Identification" round, the goal is to identify the excessive color in the image on the right. For instance, if the image on the right looks greener than reference image (on the left), the answer would be "green."
• In a "Correction" round, the goal is to make the images match. You have the ability to add any of the six colors to the image. When you think you've got it, you'll hit the "submit" button to see if you were correct. There is also a reset button which restores the image you're correcting to its original state. An example: the correction image looks a little too cool to you. You start adding a little yellow to warm it up, but something doesn't look right. You press "reset" and the image returns to its starting place - a little too cool. This time, you start adding a little red, which seems to be on the right track. Once it looks the same as the reference image, you press "submit."

You can play the game with any of the relevant colors. At first, we recommend playing with all the colors. Once you have played enough games for your statistics to be useful, you can begin to practice with the colors that challenge you the most. These differ from person to person, so you can create whichever combinations seem interesting to work with.

After Playing

Once you have a few games under your belt, you'll see a few different statistics.

You can see your overall accuracy by color, which factors in all of the games you've played so far. When you start to see trends emerge, this can guide your future practice if you want to take a targeted approach.

You'll also be able to select a difficulty level and see the trend of your scores for the games you've played on that level.

If you navigate to "Past Games" in the menu, you can see all of the games you've played. Each of them can be viewed individually.
