Browser game example
Tap a numbered square to follow an across clue or switch to the down clue. A built-in keyboard keeps the puzzle playable on a phone, and a check option lets the player review answers while solving.
Puzzle files are checked so an impossible grid is rejected instead of shipped. That rule matters for a crossword: every clue and crossing answer must agree, or a player can reach a dead end through no fault of their own.

Tap a numbered square to follow an across clue or switch to the down clue. Use the sample to name the audience, the main action, and the smallest useful first version. Cleo HQ then helps turn your own brief into a product plan and a working build.
Tap a square to select it, then tap again to switch the direction when both an across and a down answer use that cell. The numbered grid keeps each clue connected to its space. A built-in keyboard lets phone players enter letters without opening a separate keyboard.
A check-my-answers toggle can flag a square that does not fit. The game also times a solve and keeps personal bests. Those tools help players decide whether they want a hint while preserving the work they have already done. Short clues and a clear grid help a player move between an easy first answer and a tougher crossing.
The game accepts custom puzzles as a data file and rejects a puzzle that cannot actually be solved. That guard protects players from a bad clue crossing that would make completion impossible. A founder adding their own clues should test the whole grid, not just proofread each question alone.
