Crossnumbers - Puzzle Games for Android

Quick summary

Crossnumbers is a free Android puzzle that blends number puzzles with deductive logic. Players complete grids by placing numerals based on given clues so that every cell satisfies two crossing equations. The game emphasizes careful reasoning and arithmetic rather than guessing.

How the puzzles work

• Read numeric clues and determine which values fit into the grid.
• Insert numbers so each filled cell completes both the across and the down expressions.
• Use step-by-step deduction and arithmetic to eliminate possibilities; guessing is discouraged and not required.

Increasing challenge

• Puzzles grow tougher as you progress, introducing multiplication, division, and more complex clue interactions.
• Each level is designed to have a single valid solution, encouraging strategic planning and methodical work.
• Complexity scales smoothly to develop sustained problem-solving ability.

Play style and benefits

• Offline play is supported, so you can solve puzzles without an internet connection or timers.

Final notes
