If you remember only one strategy rule from this entire site, make it this: work from the top down. It is the single habit that separates players who clear boards from players who get stuck. This guide explains why top-down beats sideways, which layouts punish sideways play hardest, and the common mistakes that undo it. For the full strategy set, see our strategy guide.
Why Top-Down Beats Sideways
A tile buried under others is locked, and the only way to free it is to clear what is on top. If you waste the easy edge pairs early, you often find yourself with no way to reach the tiles you need later. Working top-down means you always remove the highest tiles first, which steadily frees everything below them. Sideways matching feels productive but regularly locks the board five moves later.
Where the Rule Matters Most, Measured
Top-down matters in proportion to stack depth, and our measured clear times show exactly where that is. The flatter the layout, the less the rule does for you; the deeper the stack, the more it decides the game:
| Layout | Avg clear | Stack character |
|---|---|---|
| Classic | 3 min | Almost flat; top-down barely matters, anything works |
| Turtle | 4 min | Single central dome; clear the dome first and the rest follows |
| Tower | 7 min | Pure vertical stack; the rule is the whole game |
| Blade | 7 min | Tall central spine; peak tiles gate the midgame |
| Great Wall | 8 min | Deep rows plus height; our hardest-rated layout |
Notice the pattern: Classic is flat and forgiving, so beginners can ignore the rule and still finish in 3 minutes. Tower and Blade are vertical puzzles where ignoring the rule is the most common reason for a dead board. If you want to see the rule decide a game, play Tower.
Spotting the Stack
Before your first match, identify the tallest part of the layout. On the Turtle, that is the dome in the center. On Tower and Blade, it is the peak. That tall stack is your priority. Any match that removes a tile from the top of the stack is almost always a good move; any match that removes a tile from the flat edges while the stack is untouched is usually a bad one.
Common Top-Down Mistakes
- Matching easy edge pairs first because they are visible and obvious.
- Forgetting that a tile can also be locked from the side, not just from above.
- Removing top tiles whose match is still buried, which gains nothing.
Frequently Asked Questions
Should I always clear from the top?
Almost always. The rare exception is when a top tile’s match is buried deeper, in which case clearing it gains nothing.
What if the top tile has no match available?
Clear nearby tiles until the match becomes playable. Patience at the top of the stack is usually rewarded.
