## Description

ZenSum is a number puzzle built on one simple idea: switch on the right cells so every row and every column adds up to its target.<br><br>No arithmetic drills, no guessing. Every puzzle has exactly one solution, and it can always be reached by pure logic.<br><br>HOW TO PLAY<br>• Each row and column shows a target sum.<br>• Tap a cell to switch it on, hold it to cross it out.<br>• The small number beside the target tells you how much is missing (−) or over (+).<br>• Solve it in as few moves as the solution needs and the stars are yours.<br><br>WHY IT FEELS GOOD<br>• You can&#39;t get stuck. Wrong moves are corrected for you, so a puzzle never dies in a knot of your own mistakes.<br>• You learn it in seconds. The tutorial shows, it doesn&#39;t lecture.<br>• Nothing counts down. The clock only decides your speed bonus — take a minute or take ten.<br><br>WHAT&#39;S INSIDE<br>• Campaign — levels that start at 4×4 and grow, with three stars to chase on each.<br>• Daily challenge — the same puzzle for every player, every day. Keep your streak and share your score.<br>• Free play — pick the grid size and difficulty you&#39;re in the mood for.<br>• 18 colour themes, 14 of them unlocked simply by playing.<br>• Combos, move economy and speed bonuses for players who like to optimise.<br>• Plays offline. No account, no sign-up.<br>• Available in English, Czech, German, Spanish, French, Hindi, Chinese and Arabic.<br><br>Two hearts, one solution, five minutes of quiet. That&#39;s ZenSum.
