We know that as we age, the brain shrinks, and this can cause cognitive changes such as difficulty focusing, memory problems, and issues with multitasking.
There are ways for seniors to stimulate their brains to keep them functioning at their best. One of these ways is for caregivers to offer games for seniors.

A puzzle is a popular game. In stores, we can find many puzzles with varying levels of difficulty.
Using a puzzle can have educational objectives.
If we want to teach seniors something, a lecture may be boring, and they will remember little from it.
A more effective way may be to prepare a puzzle.

In the “European Union Citizen” project, we used this game to teach and recall the fundamental values of the EU.
We prepared a paper board. We placed schematic and symbolic pictures and basic words (EU values) on it.
This game is simple and does not require much effort, so success can be achieved quickly.
We did not want the senior to get tired or discouraged.
The quick success encouraged participants to read the words.
Reading EU values aloud can be a start to discussion.

The advantages of the game are: easier to remember EU values, active method, improves manual skills, improves observation skills.
