## What is Reactor Grid?

Reactor Grid is a tactical board game for iPhone where small moves turn into huge swings.
A sleek one-more-turn strategy duel where every orb can start a massive chain reaction.
Place orbs on a square board, build pressure across corners, edges, and center cells, then unleash bursts that spread only up, down, left, and right. 
Any enemy cell hit by your reaction flips to your color, so one well-timed move can reverse the whole match.


## Version history (last 2 releases)

### 3.3 — 2026-09-02

Reactor Grid 3.3 makes every match more stable, consistent, and lively.
- The interface now works in either upright portrait direction while landscape remains locked.
- Improved layouts keep the menu and controls comfortably on screen across compact and large iPhones.
- The interactive tutorial now includes game sounds, and enabled sound remains audible with the hardware silent switch on.
- Player-name editing and game panels now stay correctly positioned and oriented.
- Changing the opponent type or board size now ends the previous unfinished match, and switching between computer and two-player modes resets the score counters.
