## What is Ring Rush?

A fresh take on dynamic visual training, built around the "Landolt ring" (C-shape) used in classic eye exams.
The rule is simple: spot the gap in the ring and swipe in that direction—fast.
Simple to learn, deep to master, designed for focused mini-sessions of just a few minutes.

▼ Perfect for
- Anyone training reflexes or dynamic vision
- Athletes and esports players sharpening performance
- Commuters and break-takers wanting a quick brain workout
- Score chasers who love seeing themselves improve

▼ 5-Phase Progression
Rings get smaller, faster, and more complex as you climb.
- Phase 1: 4 directions / large rings to learn the basics
- Phase 2: 8 directions / medium rings to sharpen judgment
- Phase 3: Speed reads + shrinking rings + timer
- Phase 4: Multi-ring (×2) to train parallel processing
- Phase 5: Hard mode / fake rings / fast timer

▼ Key Features
- Classic mode: Endless climb through every phase
- Practice mode: Drill the phases you struggle with
- Daily Challenge: Compete on a fresh seed every day
- Global Ranking: Compare your scores worldwide
- Stats & Graphs: Track score, reaction time, and phase distribution
- Achievements: Unlock more the more you play

▼ What You'll See Measured

Check your dynamic vision in real numbers after every run.

▼ Built With Care
- One-handed, friction-free controls
- Snappy, distraction-free pacing

## Version history (last 5 releases)

### 1.2.1 — 2026-05-03

Improved how matches end. Previously a match finished the moment only one player remained alive, which let the last survivor coast to victory even after later mistakes. From this version, matches now continue until every player is eliminated, so the final survivor must keep playing until their lives run out.

Battle mode got a major upgrade!

- Random Match and Create Room now let you choose between 2-Ring and 3-Ring rules
- Create Room also lets you pick Hearts (1-3 lives)
- Tap "Rematch" after a battle to instantly play again with the same opponent
- Winner is now decided by final score: even if you run out of hearts first, you can still win by score
