Violet Gem Necklace : 2MM 1
You pressed the correct button.
A circle has 0 vertices. A triangle has 3 vertices.
For their sum to become 9, both values must be raised to the third power.
And if you subtract 3³ from 4³, you get 55.
The answer was cubing.
A section of the wall beneath the buttons slides open. Inside, resting in a small recessed space, is a coffer set with a glowing blue gem.
You reach in, take the treasure, and secure it.
After claiming the coffer, you leave the area.
You escaped the mansion.
You successfully obtained the treasure.
Congratulations!
After securing the Blue Gem Coffer, you return to your hideout.
You stand before a desk in your base and place the coffer on top. Then you set down the 18 colored gem treasures you’ve collected so far—along with the two additional treasures you had stored away:
the treasure obtained by pressing buttons based on a sign (Game 17 / rg17)
the treasure obtained by pressing buttons based on a framed painting (Game 18 / rg18)
Now, a total of 20 treasures sit on the desk.
The blue gem on the coffer begins to glow. The coffer opens on its own, and streams of light extend toward the surrounding treasures. One by one, the 20 treasures turn into glowing orbs of light and drift into the open coffer.
When all the light-orbs have been absorbed, the coffer closes automatically.
Click.
You hear the sound of a lock.
The blue gem stops shining.
You have safely sealed all 20 treasures.
Your mission was to collect and seal the twenty treasures—and you have completed it.
You didn’t cast any magic yourself. This is simply what the coffer does: once you place it near the treasures you’ve gathered, it automatically seals them.
The coffer is safe to touch.
You sealed the treasures securely.
Mission Complete! Congratulations!
