Openings in these games are almost never chosen. They are noticed, which is a different thing, and the difference costs more levels than any other single habit.
Why the obvious match is obvious
Eyes land on the upper middle of a screen first, and boards are designed knowing that. So the match you notice within a second is usually near the top, and a match near the top is the least useful move available, because tiles fall downwards and clearing high disturbs almost nothing beneath it.
That is the whole trap. The move is not bad because it is easy; it is bad because the reason you found it has nothing to do with whether it helps.
What a good opening does
- It moves the most board. A clear low down pulls every tile above it into a new position, and some of those positions match by accident.
- It works towards the goal's location. Not the goal colour, the goal's position. If the level wants something cleared in the bottom-left, the opening belongs in the bottom-left.
- It leaves the board legible. An opening that scatters everything makes the second move guesswork, which matters more than it sounds on a tight level.
A default that works on unfamiliar boards: ignore the top third entirely for the first two moves. It will be replaced by the refill within a few turns anyway, so nothing there is worth spending an opening on.
A repeatable opening routine
- Read the goal panel and note what the level wants.
- Find where the goal lives on the board. This is the step people skip.
- Look at the bottom two rows for any legal match, however small.
- Prefer a vertical clear where one exists, because it pulls a whole column rather than nudging three.
- Check what sits directly above your intended match. Those tiles are what lands in the gap, and if they share a colour the chain will very likely continue on its own.
The routine takes about five seconds at first and two seconds once it is habitual. It is the highest-value five seconds in the genre.
The second move, which nobody plans
Openings get discussed and second moves do not, which is odd because the board after the first move is the one you actually chose. Having made a deliberate opening, it is worth a moment to look at what the cascade produced before reacting to it.
Specifically: did the drop create a special you did not intend, did it merge two clusters of the goal colour, did it open a column that was blocked. All three are common and all three change what the second move should be.
Where the routine changes
Two board types invert part of it.
On boards where something must be raised rather than cleared, the fill enters from below and clearing directly beneath the object is what lifts it, so the usual advice about clearing low still applies but for a different reason and with a much narrower target.
On boards where you draw a path rather than swap, where the path ends matters more than what it removes, so the opening question becomes where do I want the growth rather than where do I want the clear. The bottom-first principle survives; the reasoning behind it changes.
Testing it on yourself
Take any level you have already passed and play it twice: once opening with the first match you notice, once opening with the lowest legal match on the board. Note the moves remaining at the end of each. The difference is usually larger than people expect, it is visible after a handful of levels, and it is considerably more convincing than being told.
