Neck Suika

About Neck Suika

Neck Suika is a merge puzzle in a box: lean to aim, nod to drop. Identical fruit that touch merge into the next fruit up an eleven-step chain that runs Cherry, Strawberry, Grape, Clementine, Persimmon, Apple, Pear, Peach, Pineapple, Melon, and finally Watermelon. If the pile crosses the overflow line and stays there, the run ends.

The reason it works so well with head control is that dropping is the only timed action and everything else is deliberate. Aiming is continuous — your head position across a 0.055 range maps to a position along the top of the box — and there is a 0.55-second cooldown between drops, so the game paces itself at roughly the speed a neck can comfortably work. The nod that triggers a drop uses a press threshold of 0.02 and a release at 0.009, which is a deliberate hysteresis gap: it stops a single slow nod from registering as two drops.

The overflow rule is forgiving on purpose. You get a 2-second grace period above the line rather than instant death, which means a bad drop that stacks high can still be recovered by merging underneath it — the difference between a puzzle and a punishment.

How to play

• Lean your head left or right — move the drop position along the top of the box
• Nod your head down — drop the current fruit
• Arrow Left/Right to aim, Space or Down to drop; the mouse works too
• Two identical fruit that touch merge into the next size up
• Crossing the overflow line for more than 2 seconds ends the run

Tips & tricks

• Keep the big fruit at the bottom and to one side. The eleven-step chain only pays off if your large fruit are not scattered across the surface blocking merges underneath.
• Drop small fruit into gaps, not on top. A cherry that rolls into a pocket between two larger fruit is doing work; a cherry sitting on the summit is dead weight near the overflow line.
• Use the 2-second grace period. Going briefly over the line is survivable, so when you stack high, look for the merge that collapses the pile rather than panicking into another drop.
• Do not rush the nod. The press-and-release thresholds are deliberately separated to prevent double drops, so one clear nod is more reliable than a quick bob.
• Aim with small leans. The full width of the box maps to a modest head range, so an exaggerated lean pins you to the wall and wastes the drop.

Frequently asked questions

Eleven steps: Cherry, Strawberry, Grape, Clementine, Persimmon, Apple, Pear, Peach, Pineapple, Melon, and Watermelon.

When does the game end?

When the pile stays above the overflow line for more than two seconds. Briefly crossing it is survivable.
