One-tap chain reaction game: 7 tips to chain more
A one-tap chain reaction game looks like luck: you tap once and watch. It is not. In Jellyquake, a free browser game from the Plainwork Arcade, the same board gives wildly different results depending on where that single tap lands. These are the things we learned tuning it with a headless auto-player that tried hundreds of taps on the same boards, written as plain tips you can use in any Boomshine-style game.
How a round works
You get one tap per round. The tap sets off a shockwave. Every jelly it reaches pops after a short fuse and sends out its own shockwave, which pops (and shoves) its neighbours. You must pop a target share of the board: 32% in round 1, rising about 5.5 points a round, to 86% late in a run. Miss it and you lose one of three hearts. Clear the whole screen and you earn +50% points and a heart back.
Seven tips for choosing your tap
- Do not tap by reflex. Pause during aiming (the timer only matters for the clip) and look at the whole board. Look for the spot that touches the most distinct clumps, not simply the biggest one.
- Think in bridges, not clusters. A chain dies at a gap wider than a shockwave. Before you tap, trace a path from jelly to jelly across the board: the best tap starts a path that crosses the gaps, usually through a chain of mid-sized jellies spaced closely.
- Big jellies are fuel. A big jelly bursts into three hot babies that fly out and pop whatever they hit. They are the best way to cross a gap, so make sure your chain reaches one early.
- Zap jellies jump gaps. A zap sends lightning to its 4 nearest jellies, even across empty space. Put a zap between two clumps and it joins them.
- Bombs pop a wide circle. A bomb has a huge shockwave, around 200 px. Tap near one only if its circle covers jellies the rest of the chain would miss.
- Save the star for a long chain. A star doubles the multiplier for the rest of the chain. Points per pop are 10 × chain position × multiplier, so a star reached early in a long chain is worth far more than one reached at the end.
- Armoured jellies cost a hit. The first hit only cracks the shell. A chain that reaches an armoured jelly twice will pop it; one that touches it once will not.
Why long chains score so much more
Points for each pop are 10 × its position in the chain × the current multiplier, so the total grows roughly with the square of the chain length. With no multiplier, a 20-pop chain is worth 2,100 points and a 60-pop chain 18,300: about nine times as much for three times the pops. That is why the best tap on a board is almost always worth far more than an average one, and why it pays to spend a few seconds looking.
What the numbers looked like
| Round | Random tap meets the target | Best tap meets the target |
|---|---|---|
| 1 | about 60% of the time | always; clears the screen on about 30% of boards |
| 10 | about 10% of the time | always |
These come from our own auto-player on Jellyquake's boards (random taps against the best tap found on a 40 px grid). A human will land between the two, so early rounds forgive a casual tap and later rounds reward a careful one.
Play the same board as a friend
Every Jellyquake board comes from a seed. Share a challenge link and your friend plays exactly the same boards against your score. The daily board is the same for everyone each UTC day, so you can compare taps without spoilers. After a round you can also save the best chain as a vertical video clip.
Jellyquake is free, has no ads and needs no sign-up. An optional $3.99 Supporter Pass adds cosmetic themes and a Zen mode; it never changes scores or the daily boards.
