Execution

Left click, right click. Left click places a sun. Right click places a moon. This skips the toggle cycle entirely. Instead of click-click to get moon, you get it in one.

Optimizing mouse paths. Plan your click order to minimize cursor travel. If you’ve deduced three cells in a row, fill them left to right in one sweep instead of jumping back and forth across the grid.

Two-handed tapping. On a phone or tablet, try using both hands. One works the left side of the grid, the other works the right. This cuts the distance each finger travels, so you spend less time moving between cells. One caveat: if both fingers tap simultaneously, the UI would discard the input. Slow down just enough to avoid multi-touch. A misclick costs more than the fraction of a second you saved by rushing.

Sweep direction. When filling multiple cells, sweep top to bottom so your finger moves away from the cells you just tapped. This keeps them visible, letting you confirm each sun or moon registered correctly. For horizontal sweeps, go left to right with your right hand, or right to left with your left hand. The idea is the same: your finger clears the cells behind it instead of covering them. Sweeping the wrong way blocks your view, and mistakes go unnoticed until later.

Stylus (Apple Pencil, etc.). A stylus tip is more precise than a fingertip, so you hit the right cell on the first try more often. It also blocks less of the grid from view, letting your eyes stay ahead of your hand. If you play with one hand, a stylus is a clean upgrade. If you rely on two-thumb speed, it may slow you down.

Eyes ahead of hands. While your hand fills the current cell, your eyes should already be scanning the next target. Deduction and input should overlap, not alternate.

Stay loose. Tension in your hand slows fine motor control. If you catch yourself gripping the mouse or jabbing the screen, relax. Speed comes from fluid movement, not force.

Weekly difficulty curve. LinkedIn Tango puzzles are easiest on Monday and hardest on weekends. On easy days, don’t get overwhelmed by the abundance of clues or overthink the grid. Pick a promising region and start solving immediately.
