Solving the maze

1. Write down the 4 flashing numbers in order starting from anywhere.
2. Calculate 5 numbers where nth number is the sum of all digits on nth position.
3. Modulo all of them by 8 and Add 1 to the first 4 numbers.
4. First 2 numbers: starting row and column. 3rd and 4th numbers: goal row and column (top-left is 1,1).
5. 5th number: odd -> left maze, even -> right maze.

Red cells are walls. Navigating into a wall will strike and show the current coordinate. Upon reaching the goal an indicator will start flashing.

Decoding the numbers

Reorder the 4 initial numbers (called Ni below) starting from the one which flashes alongside the indicator. Calculate 4 shifts (Di means ith digit). If any shift ends up less than 10000 add 10000.

• S1 = floor((N1 ^ 2 + product of N1 digits) % 88889)
• S2 = floor(((D1 of N1) + (D2 of N2) - (D3 of N3) + (D4 of N4) + 10) % 88889)
• S3 = floor(((N3 * N1) / (N2 * N4) + 9999) % 88889)
• S4 = floor((((D3 of N3) * N4) / (N2 - (D3 of N1)) + 11111) % 88889)

Calculate the following:

• End numbers: Ei = Ni + Si
• (E1 - E2 + E3 - E4 + 1000000) % 44445. Modulo each digit by 5 and submit.

Solving the maze AGAIN

1. Perform steps 1, 2 and 5 from "Solving the maze" section for the new numbers. The 5 numbers at this point will be called Ci.
2. Modify C1: add D1 of old N1
3. Modify C2: add D5 of old N1
4. Modify C3: maze 1 -> add plates, maze 2 -> add ports
5. Modify C4: maze 1 -> add holders, maze 2 -> add batteries
6. Perform steps 3, 4 from "Solving the maze" to solve the module.

If any button is pressed out of place, such as arrows in "Decoding the numbers" or buttons in "Solving the maze" and "Solving the maze AGAIN", a strike will be given.
