The initial stages of Challenge Mode (roughly skins 1-10) are designed to ease you into the game. The Timeline speed is relatively slow, giving you ample time to plan your moves and react to falling blocks. This is the perfect opportunity to solidify your understanding of basic block placement and 2x2 square formation.

Key Strategies:
- Focus on Basic Clears: Don't worry too much about complex chains yet. Concentrate on consistently forming 2x2 squares and keeping your playing field clear.
- Observe the Timeline: Pay close attention to the Timeline's speed and how it clears blocks. This rhythm will become second nature as you play more.
- Practice Rotations: Experiment with both clockwise and counter-clockwise rotations to quickly orient blocks.
- Keep the Bottom Clear: Try to clear blocks from the bottom of the screen upwards. This prevents blocks from stacking too high and gives you more room to maneuver.
- Identify Block Patterns: Notice how the 2x2 blocks are composed (e.g., two of one color, two of another; or a diagonal split). This helps in anticipating how they'll fit into your existing structure.
These early skins are forgiving, so use them to build confidence and muscle memory. Skins like 'Shinin'' and 'Mekong' are common early appearances, offering a relaxed pace.
