ARDUUM is an ingenious sliding puzzle and more than just a simple pastime.
ARDUUM offers nine different difficulty levels so that your strategic thinking skills can be increased in a simple and playful way.
ARDUUM is not only entertaining, but also educationally valuable.
ARDUUM is about finding a strategy to move the jewels into the right position.
ARDUUM tasks can be tricky and often require lots of trial and error before they can be solved. This promotes patience and perseverance, important skills in many areas of life.
Every move requires thoughtful planning, and every solution brings a sense of accomplishment and satisfaction.
ARDUUM requires important cognitive skills such as problem solving, logic and concentration.
In addition to the ability to concentrate and solve problems, ARDUUM particularly promotes recursive, strategic, logical and critical thinking as well as spatial imagination and creativity.
ARDUUM is a challenge for the mind, a game that seems simple at first glance, but upon closer inspection reveals complex tasks.
ARDUUM offers a fun way to train the brain while instilling a sense of achievement and satisfaction when a task is completed.
Thanks to the self-explanatory rules, ARDUUM is the ideal brain game for children and adults and a perfect activity to combat boredom, which requires a good dose of puzzle skills.
The aim of the game is very simple:
All jewels must be placed inside the box.
No jewel may overlap with another.
Jewels can only be moved left and right.
(In portrait format only up and down.)
Jewels of the same color are connected to each other by a mystical force and always move synchronously.
Optionally, the player can try to solve the task using time measurement. Simply clicking on the timer turns the clock on and off.
Double-clicking on a jewel will lock it in its current position inside the box, as will all other jewels of the same color.
Pinned jewels will appear yellow in the box, if the position is correct.
If the position does not correspond to the solution, the player receives a time penalty when playing against the clock.
The box in which the jewels are to be placed is 4x4 squares in level 1 and 8x8 squares in level 9.
In some difficulty levels the positions of some jewels are given (yellow jewels), in other levels you have to find the correct positions for all jewels.
Every task has exactly one solution. No task has no solution and no task has more than one solution.

The tasks at the easiest level of difficulty can be solved quickly in just a few moves, while the tasks at higher levels require a fair amount of thought and tactical skill.

The nine difficulty levels are designed so that even preschool players can solve the easier levels.
The higher levels particularly challenge adults' logical skills!
