Very unique. Took me ages to get my head around the logic required to solve these puzzles. Still not sure if I can explain it to someone else - but here goes.
Its actually very different to your normal puzzler, and can thus be frustrating - so Rule 0: Stop thinking, and start THINKING!!
Rule 1: To finish a level the coloured boxes must be on the matching coloured tile.
Rule 2: When you click a tile, the first box north, east, south, and west of the tile move towards that tile.
Rule 3: Boxes can only move over tiles, so stop moving when they reach a "hole" OR when the box reaches the tile adjacent to the tile clicked.
Rule 4: When you click a tile with a dot, the first box north, east, south, and west of the tile move AWAY from that tile.
Rule 5: Boxes also stop moving when they reach another box.
Rule 6: You can only click an empty tile LINKED to the last tile you clicked by empty tiles. The last tile you clicked is highlighted by the spinning square.
Observations (the first two you need to know to play, the rest are like hints!):
* Boxes show the colour of the tile they are sitting on through their center.
* Grey boxes are just there to get in you way. Some can be moved, other can't be moved (these have four dots (like bolts)). They don't always need to be moved to solve the puzzle - but if they are sitting on top of a coloured tile, then they need to be moved!
* You can move a maximum of four boxes, one in each direction around the tile you click. Because of Rule 6, this is usually a bad idea, as if they move towards the clicked tile you'll (typically) end up boxed in.
* Rule 6 is the doozy - you need to plan ahead so you don't box yourself in!
* MOST clicks I made was to move only ONE box at a time - this was to avoid getting boxed in! There will be times when you have to move more than one box per click - this is part of the puzzle!
* Often your FINAL click will leave you boxed in. That's OK - you've completed the level, so no problems.
* Some puzzles can be completed in stages: i.e. as you play, you box out (lose access to) areas of empty tiles; while some puzzles you are boxing out, then opening up areas of empty tiles all the time.
* Boxes on the edges of the tile field can be the most tricky - if you move them away from the edge, you may NEVER get the box back to the edge of the field. (This really depends on the level, and if there is an appropriately placed dot tile - but in most case it is best to be wary of moving them away, unless you absolutely have to).
* Most puzzles RELY on your ability to attract boxes to the tile you clicked - this means unless you are completing the puzzle, you should plan ahead to ensure you have boxes you can move around!
* There is an undo button - use it! If you long-click on the undo button it will reset the puzzle. Reset the puzzle only when you've forgotten what moves you made! That's a hint too: remember what moves you've made (so you don't sit there repeating them!) (most of the puzzles I took ages on was because of this!!)
An in-game tutorial that covers each of these rules and some of the observations would have been nice. (Max one rule or observation at a time! Anything more is a crash course! That makes that level one intro a bit of a train crash!!)
It's a great game - and even when I worked out what was going on, it still took ages to solve some puzzles.
