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.
