Oil Tycoon Sudoku - Brain Game

Turn a logic puzzle into an oil hunt. Oil Tycoon Sudoku combines Star Battle-style deduction, careful drilling, and a weekly goal for your region. Each grid hides exactly one oil barrel in every row, column, and colored region. Barrels cannot touch, even diagonally. Follow the clues in the grid to find the oil, with no numbers to fill in. MARK FREELY. DRILL CAREFULLY. Tap a cell to mark or clear an X, or drag to mark several cells at once. Marking does not use drill durability. When you have worked out a barrel's location, double-tap an unmarked cell to drill. A wrong drill costs durability, so think through each move before you commit. TURN DEDUCTION INTO DISCOVERY Reveal red oil barrels in a colorful oil-field setting. Chain accurate drills for GOOD, GREAT, OIL STRIKE, and BLACK GOLD feedback as you work toward clearing the grid. MAKE EACH SOLVED GRID COUNT Complete levels to add in-game oil output to your assigned region. Follow your region's progress in the weekly Region Output Ranking and see how your solved puzzles contribute to its total.
