Echo Pop

Echo Pop is a one-tap chain-reaction bubble game. Tap any bubble on a slowly drifting field and its shockwave detonates same-colour neighbours within reach, which detonate their own neighbours, racing through the field as a chain. You have 60 seconds per run, and quadratic scoring (chain² × bonus) rewards patient, well-read taps that trigger huge chains.

How to play

  1. Watch the bubble field. Same-colour bubbles drift in clusters; let them grow before you commit.
  2. Tap any bubble to detonate it. Its shockwave reaches every same-colour bubble within ~38 world units.
  3. Each newly-popped bubble emits its own shockwave, propagating the chain further across the field.
  4. Score = chain length² × bonus. Chains of 8+ multiply by 1.5×; chains of 15+ multiply by 3.0×.
  5. After 60 seconds the run ends. Try to beat both your highest total score AND your largest single chain — two separate leaderboards.

Tips

FAQ

Why is my chain score so much bigger than my single-pop score?
Echo Pop uses quadratic scoring: a chain of N pops scores N² points. A 10-chain is 100 points, ten 1-chains is only 10 points. The game is designed to reward predicting the cascade, not spam-tapping.
How does the shockwave decide what to chain?
Each pop emits an outward-expanding ring at fixed speed. Any same-colour bubble the ring's leading edge crosses within ~350 milliseconds becomes the next pop in the chain. Out-of-range bubbles are not touched.
Does the field get harder over time?
Yes. The run has three implicit phases: warmup (slow spawn rate, 5 colours), push (faster, 6 colours), and crunch (densest, 7 colours). Later phases reward big chains more because clusters form quickly.
Are there power-ups?
Not in v1. Echo Pop is intentionally a pure 'predict and tap' loop — the only tool is your read of the field. Power-ups may come in v2 if they don't dilute that focus.

Echo Pop

回声炸开是一款一击触发的链式爆炸气泡游戏。画面上的气泡缓缓飘动,点击任意一颗,它的冲击波会引爆射程内所有同色气泡,后者也会发出自己的冲击波,把连锁扩散到整片画面。每局 60 秒,得分按链长平方计算,鼓励耐心读场、看准一次性引爆大簇。

玩法

  1. 观察画面,等同色气泡飘到一起形成簇 —— 不要急着点。
  2. 点任意一颗气泡触发引爆。它的冲击波可触及射程 ~38 单位内的同色气泡。
  3. 每颗新引爆的气泡都会发出自己的冲击波,把连锁继续传播。
  4. 得分 = 链长² × 奖励倍率。8 链以上 ×1.5,15 链以上叠加 ×2(总 ×3)。
  5. 60 秒后本局结束。尝试同时打破历史总分和单击最大连锁两个独立纪录。

玩法技巧

常见问题

为什么大连锁得分远高于单点?
回声炸开用平方计分:N 链得 N² 分。10 链 = 100 分,十次 1 链总计仅 10 分。整个机制就是奖励"读到机会并一次拿下"。
冲击波是怎么决定下一个引爆目标的?
每颗气泡爆开时会发出一圈定速扩散的圆环;凡是被这圈环在 350 毫秒内触达的同色气泡,都会进入链条作为下一个引爆点。射程外的不会被波及。
时间越久会越难吗?
会。一局有三个隐式阶段:0–15 秒预热(5 色,慢生)、15–40 秒推进(6 色,更快)、40–60 秒压迫(7 色,最密)。后期奖励更大,因为簇形成更快。
有道具系统吗?
v1 没有。回声炸开有意保持"读图 + 点击"的纯粹循环。如果未来道具不会稀释这个核心体验,可能会在 v2 加入。
