Unchi Island is a magical island divided into 5 peninsulas, which communicate one after the other forming a kilometric straight line.

– The first peninsula is called the Verdi peninsula, because of the green pastures and vegetation that run the length of the peninsula.

– The second peninsula is called the Aqua peninsula, because of its bluish land, very similar to the water that surrounds it.

– The third peninsula is called the Rosso peninsula, because of its reddish soils due to its many red minerals.

– The fourth peninsula is called the Viola peninsula, for its violet-coloured soils that resemble the colour of a violet chalcedony.

– The fifth and last peninsula is called the Pearl peninsula, because of its golden-coloured, mineral-rich soil. It is also where the king and queen of the magical Unchi Island live.

No one knows where it comes from, or why it is magical, but everyone knows that joy and kindness are the main qualities of its inhabitants.

Every 4 years, King Unchigo and Queen Unchika hold the national mathematics tournament, where the bravest and most intelligent adventurers face an endless number of tests, each one more difficult than the last.
After solving several operations in each peninsula, they will have to face their current champion in the final test in order to get the pass to the next peninsula and a special reward.

Whoever manages to solve all the operations and beat the current champions will become the new Unchi Island champion.
