Iris Bloom

Iris Bloom is a stained-glass radial rotation puzzle. A central iris is built from concentric rings, each divided into the same number of coloured sectors. Your goal is to rotate each ring so that the colours line up across every shared edge between adjacent rings — when every edge matches, the iris snaps into bloom. Five difficulty bands from Petal (3×4) through Eclipse (6×8) scale both the ring count and the colour palette; the generator enforces aperiodic ring patterns so each puzzle has a unique solution. Daily mode shares one puzzle worldwide per day; endless mode reshuffles on every reset.

How to play

  1. Press on a ring to grab it; drag around the centre to rotate.
  2. Release to snap to the nearest sector step — one snap counts as one rotation.
  3. Mismatched edges show as faint dotted hairlines; matched edges fade out.
  4. Use the hint button to highlight the ring furthest from alignment.
  5. Solve in as few rotations as possible — best stays on a no-hint run.

Tips

FAQ

Is Iris Bloom free?
Yes. Iris Bloom runs free in your browser on desktop and mobile, with no installs, sign-up, or downloads.
Why doesn't my best save when I use a hint?
Using a hint disqualifies that run from the personal-best record. Solve without hints to lock in a new best.
Are the daily and endless puzzles the same?
Daily picks a deterministic puzzle from the current UTC date — the same iris world-wide. Endless rolls a fresh random seed every time you reset.

Iris Bloom

虹膜绽放(Iris Bloom)是一款彩色玻璃风格的径向旋转拼合谜题。屏幕中央是由若干同心环组成的虹膜,每个环划分为相同数量的彩色扇区。目标是旋转每一个环,让相邻环之间的每一道共享边颜色一致 —— 当所有边都匹配,虹膜会「绽放」。五档难度,从花蕾 3×4 到日蚀 6×8 依次增加环数与色板;生成器强制每个环图样为非周期序列,保证每道题有唯一解。每日模式全球同题,无尽模式每次重置都换种子。

玩法

  1. 按住某一环开始抓取;围绕中心拖动以旋转该环。
  2. 松开时自动吸附到最近的扇区步;一次吸附计为一次旋转。
  3. 未匹配的边显示为淡点划线,匹配后逐渐消失。
  4. 用提示按钮高亮最偏离对齐的环。
  5. 尽可能少的旋转次数解出;只有不用提示的本局才会刷新最佳。
