EchoFluxNova

EchoFluxNova is a vertical sudoku puzzle mobile game centered on nine-grid logic reasoning. Players can choose from three difficulty levels: easy, normal, and hard. Tap a cell to enter a number, or switch to note mode to mark candidates. With automatic error checking and same-number highlighting, you can quickly spot conflicts and clues. Each round is timed, and you can pause at any time. After clearing a puzzle, your best time and total clears are recorded. It is easy to pick up yet challenges your strategy and patience.
