Aqua Blitz 2

Aqua Blitz 2 puts its board on the seabed and hands you a host: Pearl, a little mermaid who introduces the rules and then keeps turning up between levels. That framing does real work. A swap-and-clear board is a familiar object, and what separates one from another is usually how much company it gives you while you play.

The scale here is the second thing worth knowing. More than 700 levels is a long runway, and the difficulty is spread across it rather than stacked at the front. Early boards teach; later ones start layering goals that need a particular corner cleared rather than a particular colour counted.

What you are getting is a long, unhurried sea-themed board with a guide who explains the tricks instead of leaving you to infer them. What you are not getting is a mechanic you have never met before. The swap is the swap.

1. Trade places between two touching pieces to line up three of a kind.
2. Read the goal strip before you move — each level asks for something specific.
3. Longer lines leave a special piece behind; set those off near clutter.
4. Follow Pearl's prompts when a board introduces a rule you have not seen.

Work the bottom rows first. Pieces fall downward, so a clear made low reshuffles far more of the board than the same clear made near the top.
