Calcudoku: how a round works
Calcudoku gives you a focused activity to play in your browser. Fill a 4×4 Latin square and satisfy every cage arithmetic target. Keep the game area visible while you use its controls. Choose a comfortable screen position before beginning. Choose a clear next step rather than rushing through the instructions.
Twelve puzzles with addition, multiplication, subtraction and singleton cages.
A focus for your next round
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Refer to the controls when needed.
The objective of a round
Fill a 4×4 Latin square and satisfy every cage arithmetic target. Keep that objective in view throughout the round. Take a moment to understand the current position.

See the idea in action
A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Apply the same reasoning to the position in your own round. Consider the next action carefully.
Check this before moving on
A correct cage total does not permit duplicate digits in a row. Read the feedback to see why an action did not have the expected result. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
