Plain physics is the key thing here. i think the snake moves in 3d space and you control it with arrow keys or swipe gestures to eat numbered blocks.
Step through the 3d space, guide the snake to eat numbered blocks, and merge them to grow.
You use arrow keys or swipe gestures to move the snake in 3d space. Merging numbered blocks is the main mechanic and it makes the snake longer.
Most of the time, keep an eye on the space ahead and merge smaller tiles before larger ones to control growth. Patience is better than rushing into tight spots.
