Strategies for Solving the Trading Post Puzzle

Understanding the Puzzle’s Mechanics
The puzzle consists of:
- 4 yellow squares
- 1 pink square
- 4 grey squares
Your primary objective is to position the four yellow squares into the corners of the cube. However, this is not as straightforward as it sounds, as each square operates under specific movement rules.
Movement Rules for Each Square
- Yellow Squares: Tapping a yellow square moves it up one space only. It cannot move left, right, or down but can occupy a grey square or switch places with the pink square.
- Pink Square: This square plays a crucial role in rotating adjacent yellow squares. Each tap on the pink square rotates the surrounding yellow squares counter-clockwise, respecting the gaps between them.
Step-By-Step Instructions to Solve the Puzzle
To complete the Trading Post puzzle, follow these detailed steps:
- Begin by tapping the two yellow squares located on the middle-right. This action shifts both squares up one slot, positioning them just below the top row.
- Next, tap the pink square twice. This rotation will adjust the top-center yellow square downward, placing it right below the pink square.
- Now, select the yellow square in the middle-left. By tapping this square, it will jump up and occupy the spot of the pink square. This crucial move prepares the pink square for a more strategic rotation.
- Shift your attention to the yellow square at the bottom center. Click it twice to elevate it to the top-middle position.
- Finally, with everything positioned correctly, tap the pink square four times. Each tap will rotate the nearby yellow squares, aligning them perfectly into the corners. After completing this sequence, all four yellow squares will settle into their designated corners.
Your Reward: Opening the Cube

Once you’ve successfully maneuvered the yellow squares, the cube will open, and you will be rewarded with the Allowance Token. This special token offers a permanent upgrade, increasing your daily coin total by +2, enhancing your gameplay experience.
