Treasure Tower: a pin puzzle with 112 towers to loot

How to play

1. Look at what each chamber holds and which way every pin slides.
2. Tap a pin to slide it out; everything resting on it falls.
3. Use water to turn lava into harmless stone, and use lava to deal with grumblers before they reach Pip.
4. Get enough gold to Pip to win the tower. If Pip is burned, caught or blown up, retry and try another order.

What it exercises

It is a rescue puzzle and a physics puzzle at once, and most towers can be read before you touch anything.

• Cause and effect

  Each pin releases something, and what falls next depends on what fell before. You predict the chain before pulling.

• Ordering steps

  From level 6 on, only one order works. Finding it means thinking two or three pulls ahead.

• Spotting traps

  In the trick towers the obvious first pin is usually the wrong one, so you learn to check every outcome.

Tips

• Pour water onto lava first whenever you can; stone is safe, and a splash turns the whole pool solid.
• Bombs explode when lava touches them, so keep the two apart near Pip.
• Slanted pins steer whatever falls on them. Pull one to let things drop straight down instead.
• The left shaft in some towers is a dump. Whatever falls in stays there, which is handy for unwanted lava.
• Every tower gives you one free hint and one free skip. A hint caps that tower at two stars, and a skip counts as one.
