The blocks are falling too fast! What do I do?
In Classic Mode, take advantage of the steady speed. ALWAYS look at the preview window in the top right corner so you know exactly what shape is coming next before you commit to a drop. In Accelerated Mode, it gets crazy fast! Focus your eyes on the center of the screen, prioritize drops that will flatten out slopes, and don't hesitate to burn your 'Clear' power-up if a tower gets too high.
Does the sand just pile up infinitely? Can I control where it flows?
When a peak gets too high, new sand dropped on it will naturally slide down the slopes into lower valleys. You can use this physics mechanic to your advantage! Deliberately drop blocks on high peaks above empty pits so the sand acts like a waterfall, filling the gaps below to trigger massive multi-line clears. But beware—dropping sand blindly can cause it to spill into areas you were trying to keep clean!
When is the best time to use the Skip and Clear items?
Skip: Use this when you get a horribly shaped block that will create steep, unmanageable spikes, or when the color completely clashes with what you need for an aesthetic build. Better to toss it than ruin your board.
Clear: Save this strictly for emergencies! Use it only when the sand is dangerously close to the top "Game Over" line, or if a massive, ugly pillar is blocking all your drops. It buys you precious time to rebuild.
