Goal

Match the related items. If the author has set a maximum time or a limit on the number of lives, you will have to do it before the time and/or lives run out.
If the author has set a limited number of lives, you will lose one each time you try to match two unrelated items.
If the author has set a maximum time to complete each screen, when the time is up you will go to the next screen without being able to add the score of the unmatched items. In this case, you will also lose a life if they are finite.
The game ends when you correctly match all the items on the last screen, when you lose all your lives, or when you run out of time on the last screen.

Controls

Cellphone or Tablet

Tap an item on the left and then one on the right (or vice versa) to try to match them. If the item contains a media object, tap on the object to zoom or play it, and outside the object to select the element. The elements have connectors at the inner ends that you can use to match them by dragging and dropping.
Select an item that has audio to play it, and tap and hold on an image to enlarge it.

Computer

Click on an item on the left and then one on the right (or vice versa) to try to match them. If the item contains a media object, click on the object to zoom or play it, and outside the object to select the element. The elements have connectors at the inner ends that you can use to match them by dragging and dropping.
Select an item that has audio to play it, and tap and hold on an image to enlarge it.
You can also play using the keyboard arrows and the Space and Enter keys.

Score

You start with 0 points and work your way up to 100 depending on how many items you match correctly and how many attempts you need to do so.
If the game only has one screen, divide the total score by the number of items. For example, if there are 10 items, each item is worth 10 points.
If there is more than one screen, first divide the score by the number of screens (for example, if there are 4 screens, 25 points each screen), then within each screen divide the score for that screen by the number of items.
The first time you select an item and match it incorrectly with another item, the maximum score you can get on that item will be halved. The second time, it will be divided by four, and the third time, the score for that item will be zero.
