Study the three mermaids.

What jewelry are they wearing?

The colors of the bracelets lead to a number.

The three colored bracelets of the three mermaids lead to three correct answers. In the center of the picture around the column, the number of colored lights of the corresponding color gives you the solution. The positions of the mermaids in the picture from left to right give you the order of the numbers: orange (8), yellow (7), green (5).
Correct answer: 875

Study the pictures on the column in the foreground.

In order from top to bottom.

The number of the corresponding animal gives you the correct answer.

The three pictures on the column in the foreground from top to bottom give you the correct answer. You must count the three animals (turtle, shark, dolphin) to find the solution. The corresponding number from top to bottom gives you the correct answer. Turtle: 1, shark: 6, dolphin: 5.
Correct answer: 165

Study the three schools of fish.

Study the three measuring devices on the column.

How can you create a number from the colors?

Mix the colors!

The three measuring devices on the column from top to bottom give you the correct answer. The measuring devices each have two colors. These must be mixed to get the color you need. The value of the illuminated points on the tentacles gives you the number. First device: blue and red makes purple = 6, second device: red and yellow makes orange = 8, third device: blue and yellow makes green = 5.

Study the octopus. What is it holding in its arms?

Seahorse stands for minus, starfish stands for multiply and snail stands for plus.

The colors of the creatures reveal the corresponding value.

The octopus is holding three creatures in its tentacles (seahorse, starfish and snail). The three creatures each have an arithmetic symbol (-, x, +). The three creatures are shown in color at the bottom of the picture. The color stands for a numerical value that corresponds to the illuminated points around the column. Calculate: green snail (+5), yellow starfish (x7), green seahorse (-5), red starfish (x3), yellow snail (+7), yellow starfish (x7), green snail (+5), yellow starfish (x7), red seahorse (-3). Multiply and divide first, then add and subtract! +5×7 -5×3 +7×7 +5×7 -3 = 101
Correct answer: 101

Study the gemstones.

Count the stones.

The first three stones determine the order of the sequence.

There are red, blue and green gemstones in the foreground of the picture. The number of gemstones determines the value. The positions of the first three stones from left to right give you the order of the numbers. There are six green gemstones, eight red ones and seven blue gemstones in total.
