How to earn three stars

Judge a cluster by how many strikes it needs to reach gold, not by how many plants it contains.

A lilypad needs two strikes to become a golden lotus; a pink lotus needs one. Four pink lotuses are therefore worth far more to a chain than eight lilypads, because the wave can convert them and still have energy left to travel. Scan for pink first, every time.

Identify where you want the chain to end, then work backwards to the tap that gets it there.

The densest cluster on the board is your destination, not your target. Starting your wave inside it wastes the detonations on plants that would have been reached anyway. Start outside and arrive.

Open water is the most common reason a promising chain dies, because ripples have a finite reach.

Before committing, count the empty tiles between one gold-capable plant and the next. If the gap is wider than a single ripple's reach, the chain will not cross it no matter how good the opening looks. Find an opening on the far side of the gap instead.

Most boards contain one obvious opening that reaches exactly two stars, placed there deliberately.

If a tap looks clean and lands you just short of the target, that is usually the designed decoy rather than bad luck. The real answer is normally one or two tiles away from it, on the side with more room behind the first detonation.

Any tap can trigger one golden lotus; the skill is placing the tap so that gold's blast reaches another one.

Each detonation throws four fresh ripples from its own tile, so the second one roughly quadruples the area you cover. A chain with two detonations typically outscores a chain with one by more than double.

Two golden lotuses in the same ring of a ripple detonate simultaneously, and their blasts are queued together.

This is worth engineering on purpose. A tap positioned equidistant from two golds sets off both at once, and the overlapping blasts reach tiles that neither would have reached alone. Symmetry on the board is usually a hint that this is available.

A pink lotus that your opening wave will convert to gold can serve as a detonation later in the same chain.

Your wave does not only consume plants — it upgrades them. A pink lotus struck early in a chain becomes gold, and can then be detonated by a ripple arriving from a subsequent blast. Planning that two-stage use of a single tile is where the highest scores come from.

A wave shoves a stone one tile directly away from the wave's origin, and then stops.

Because the direction is determined by where your tap was, a stone's final position is entirely under your control. Deciding where a stone should end up, and then choosing a tap that pushes it there, is a legitimate opening in its own right.

Shoving a stone into a gap can give a later ripple a shorter distance to cross.

Since ripples die over open water, moving an obstacle can turn an uncrossable stretch into a crossable one. This is the reverse of how stones are normally read, and it unlocks a large number of late-chapter boards.

A stone absorbs a wave completely, so it can be used to stop a ripple travelling in a direction that wastes it.

Energy spent travelling across empty water toward the board edge is energy not spent on plants. Positioning your tap so that a stone blocks the useless direction concentrates the rest of the wave where it can do work.

If your opening tap did not chain, the board is very unlikely to reach the top target from what is left.

There is no penalty for restarting and no timer running, so a fresh read costs nothing but a few seconds. Grinding out a clear from a bad opening usually locks in two stars.

Campaign boards are tuned so that a single opening tap reaches the three-star target.

If you are consistently landing just under it, you have not found a slightly better version of your idea — you have not found the idea. Look at a part of the board you have been ignoring, usually a corner or the far side of a stone.

A perk used on a board you do not understand yet just moves you from one two-star clear to another.

Perks are most valuable when you can already see the chain and are one tile short of reaching it. Spending them speculatively on a first attempt is the most common way players waste them.

The daily puzzle is generated rather than hand-tuned, so it rewards general board reading rather than a designed solution.

That makes it the best place to drill the habits above without a star target hanging over it. A daily run also cannot be failed in any lasting sense — a missed day resets the streak count and nothing else.
