Inclusion method
Include a current game when touch is a documented input, the complete play loop works with a single finger (taps, drags, or swipes), and no two-finger gesture or keyboard-specific step is required at any point.
A “one-thumb” game is not a promise that every phone fits every hand. It means the play loop has no two-finger or keyboard requirement.
Why this collection exists
Commutes, queues, and leaning-back sessions often leave one hand free. This collection separates games you can complete with one thumb from games that assume a full keyboard or pointer precision.
How we decide inclusion
- Touch is a documented input on the game page.
- The complete loop (start, every move, finish) uses only taps, drags, or swipes.
- No step requires a keyboard, a second finger, a pinch, or a long-press that a thumb cannot comfortably hold.
Every current NoCharge game passes because each was designed for a phone-width stage. Board sizes are tuned so a 6×6 or 8×8 grid stays comfortable at 360 px; the guides say where a larger grid (like the future 9×9 Sudoku) may need more precision.
What you will find in the grid
Each card shows the genre, session length, and the specific single-finger action that qualifies it. Typed text is never required: Word Tile Rush submits letter tiles you already tapped, and Pass & Play names are optional session-only fields.
Limits
- One-thumb does not mean small; some sessions still take ten minutes.
- This collection makes no claim about hand size, dexterity, or comfort for every person.
- Touch targets are sized by the game stage; the large-target collection lists the most generous boards.
