Maya has been going out alone for a week.
She would leave the hotel when the sun rises and return when it sets.
She had a fixed place she visited every day.
It was Tettromino Plaza, the center of Yeterinpuurk.
There were a total of 7 types of shapes that could be formed by combining 4 squares.
J, L, T, Z, S, O, I.
These 7 blocks were arranged on the ground with no gap, each with its own color from red to purple.
The length of one square piece is 15cm.
Calculating, there were found to be 10 million square tiles here, meaning 2.5 million Tettromino blocks.
Maya walked quickly as she scanned the blocks on the floor.
There was a limit to the combinations that could be made with the 7 blocks.
Not long after examining the ground, she discovered a pattern.
Several Tettromino blocks combined to form around 500 patterns.
Maya assigned numbers to those patterns.
They kept repeating.
