Every row and every column holds 1 to n once each. The little label in each cage is the arithmetic its cells must satisfy: 12+ sums to twelve, 3× multiplies to three, 7− differ by seven and 4÷ divides evenly into four. A cage of one cell is just that cell's own number.
Click a cell to select it, then type a digit. Backspace clears it, arrow keys move. Every puzzle is checked for a single solution before it reaches you.
Fill the grid from the number clues to reveal a hidden picture.
Push every crate onto its target. You can push, never pull.
Literal boards with a stated move solution, so the level you read is the level you play. Solve inside the move budget or run out and lose.
Jump pegs over each other until only one is left on the board.
Your heartbeats, breaths and kilometres travelled around the Sun so far.
Sink the whole fleet. The AI hunts with real targeting logic, not luck.
Bricks, lives and power-ups, with the pace ramping as you clear them.
Classic rally against an AI paddle that tracks the ball.
