Tower Stack

Watch the edge, not the block

Rather than following the sliding block with your eyes, fix them on the edge of the tower below and tap the moment the block's edge lines up with it. It is much easier to judge one edge meeting another than to judge where a whole moving block is.

Find the rhythm

The block moves back and forth at a steady pace, so the moment it lines up comes round at regular intervals. Count the rhythm for a pass or two before you tap, rather than tapping on the first pass.

Flush drops are free

Land a block flush with the one below and it snaps back to full width, costing you nothing. That makes precision worth far more than speed: one careful flush drop undoes a lot of narrowing. As blocks get faster, the snap is what keeps a tall tower alive.

Choosing a speed

The tiers change how fast the first block slides and how much quicker each block after it gets. The slowest tier is a good place to learn the snap — landing flush often enough to keep the tower at full width — while the fastest starts at more than twice the speed and gains pace much more quickly with every block.

Your best score is kept per tier, so it is worth having a go at each. A high score on the slow tier and a respectable one on the fast tier are both achievements.

Recovering from a narrow tower

Once the tower has narrowed, every miss makes it narrower still, and it is tempting to rush to get it over with. Do the opposite. A narrow tower is not harder to hit squarely than a wide one — the edges are just closer together — and a single flush drop restores the full width. Slow your breathing, watch the edge, and wait for the block to line up exactly.

Where the speed catches you

Most runs end at the point where the block starts moving faster than you have practised. When you notice the pace pick up, spend one pass just watching before you commit — a missed tap costs a slice of width, but a panicked one can miss the tower completely.
