Diamond Buenos

Diamond Buenos is a quick gem puzzle. Every round highlights one cut of a sparkling sapphire, and your goal is to find the matching dark contour among six shapes before the timer runs out.

Press Start Game to begin a game of 10 rounds. Six contours are shown on the board: trillion, kite, oval, cushion, octagon and hexagon. A row of six bright gems sits below them, and the gem that glows is the cut you have to find. Tap a contour to select it, then press Confirm to lock in your answer. The selected contour rises and glows, and the board shows the right answer after each confirmation.

Each round lasts 15 seconds. A correct answer earns 40 points plus one point for every full second left on the clock, so a fast answer is worth up to 55 points. The counter at the top shows how many rounds you have solved out of 10. The game ends at the first wrong answer or when the timer runs out, so a perfect game needs ten correct answers in a row.

Tap the pause button or press back to stop the clock. From the pause window you can resume the round or leave the game. The timer also pauses when the app goes to the background.

When the game ends, you see your result and enter a name of 2 to 16 letters, digits or spaces. The Player Rating screen lists the top five scores, so you can try to pass the starting leaders Anna, Den, July, Sam and Max and take first place. Your last name is remembered for the next game.
