Orbit Blocks

You are part of the TetriXpress team, an intergalactic transport company specializing in cargo transportation across the galaxy. However, one major challenge the company faces is the lack of space in cargo ships. Your mission is to compact the cargo as much as possible, ensuring that each container occupies the least amount of space.

To measure the level of compactness, each container – shaped like a tetromino – has colored sensors on its edges. These sensors indicate how well the cargo is fitted:

• 🟥 Red → Low contact, misaligned cargo
• 🟨 Yellow → Moderate contact
• 🟩 Green → High contact
• 🟦 Dark Blue → Optimal compactness

To progress to the next level, you must keep the cargo within the required compactness range. This means there is a maximum limit of red sensors allowed and a minimum number of dark blue sensors that must be reached.

Example – Level 1:

• The cargo consists of 10 pieces.
• You can have a maximum of 3 red sensors.
• You must ensure at least 4 dark blue sensors.

Stage Limits

Check the table at the bottom of the instructions to see the expected limits for each stage.

When you stay within the allowed range, the indicators on the right panel will turn green.

⚠️ Warning!

Do not let the piece cross without properly fitting with the central piece(s), as this will result in game over.
