MineSphere 3D

MineSphere is a 3D logic puzzle with zero luck.
Turn floating relics of stone and gold, read the numbers to find every trap, and dig out all the safe cells.
There are three ways to play: Adventure, Today's board (the Daily Challenge) and Classic. Adventure and Today's board never need luck; Classic is old-school Minesweeper, where luck sometimes decides.

PURE DEDUCTION
- Every Logic puzzle board is built to be solvable from its clues alone. You never have to guess.
- Stuck? Hints guide you in three steps: where to look, the reasoning, then the answer.
- A miss cracks the board. It breaks at three cracks, but you can still finish and review where your reading went wrong.

FOUR SHAPE WORLDS
- Cube: completely free. Follow the Adventure map to unlock new mechanics: Bands and Twist.
- Pillar: a stone pillar of stacked rings. Turn the rings to swap neighbors.
- Celestial Sphere: a sphere of hexagonal cells. Only the equator ring turns.
- Crystal: a polyhedron of rhombic faces that turns in 120° steps.
The first three stages of Pillar, Celestial Sphere and Crystal are free to try.

TODAY'S BOARD (DAILY CHALLENGE)
- One board a day, the same for everyone. From October 26, Tuesday, Thursday and Saturday boards come from the Shape Worlds.
- Share your result without giving away the answer.

CLASSIC
- Old-school rules on any shape: pick cube, full 3D, sphere, cylinder or polyhedra, then a difficulty from Easy to Expert.
- Sphere, cylinder and polyhedra need the matching World Pack.
- Your best time is kept for each shape and difficulty, and your Game Center leaderboards carry on.

IN-APP PURCHASES
- Cylinder, Sphere and Polyhedra World Packs (for Pillar, Celestial Sphere and Crystal), Unlimited Play, the Premium Bundle (everything) and hints.
- Free players see ads between boards. Any World Pack, Unlimited Play or the Premium Bundle removes them.
