Choose controls that fit a smaller screen
A browser game can load on a phone and still be awkward if every important action expects a physical keyboard. The games in this collection have published control notes that mention taps, touch buttons, direct tile selection, or an on-screen action. That makes them a better starting point when the device in your hand is the device you want to use.
Touch-friendly does not mean every title uses the same layout. Some games ask for a single tap at the right moment. Others provide directional buttons, let you select a target directly, or use a board where the next move is chosen by touching a tile. Read the Controls section before launching so you know whether the game is designed for portrait play, landscape play, or a larger screen.
