5 rounds • 1 minute each • a new target every round!
• A random target (4–10) is chosen each round.
• Rows of squares sized 1 to target−1 appear in play.
• Tap a whole row to select it — no need to tap each square.
• Drag rows together to join them, then drop a row the target's size on the guide!
• Make as many as you can before the 60 seconds run out.
