Wood Block Tap Away is a 3D unblocking puzzle: wooden blocks are stacked into a shape, each pointing a direction, and tapping one slides it out — provided nothing is in its way.
The order is everything. A block that can't move now may be free after you clear something else, so the puzzle is working out the sequence rather than which blocks to remove.
Because something is in its path. Each block slides only in the direction it faces, so it stays stuck until whatever blocks it is cleared first.
Because blocks and their paths are hidden from some angles. Rotating is how you find the next legal move rather than just a camera option.
Yes — tap blocks and drag to rotate. Nothing to install.
