Water Blast

Water Blast gives you one action and asks you to think about where to use it. Tap a drop and it grows; keep feeding it and it bursts, throwing water into whatever sits beside it, which swells in turn and bursts in turn. A level is finished when nothing is left on the board.

The trick is that a chain you start well does the work for you, while a chain started in the wrong corner fizzles two bursts in and leaves you tapping the rest by hand. Stars are given for speed, so the difference between clearing a level and clearing it properly is whether you found the drop that touches everything. There are 400 levels of that question.

How to play

Clear every element on the board to finish a level. Each tap adds to a drop, and a drop that fills up explodes, spilling water onto the ones around it so they grow and explode as well. Look for the drop with the most neighbours before you touch anything, because one well placed start can empty the whole board. Stars are awarded on time, so hesitating costs you more than a wasted tap.

Controls

One tap or click is the entire game. Press a drop to make it grow, press it again to push it closer to bursting, and press a different one when you want two chains running at once. There is nothing to drag and nothing to aim, so the only decision is which drop you touch and when.
