How to play
Drag from the head to draw the snake's body from cell to cell. Slide back along the body to undo, or steer with the arrow keys.
Eat the apples in numbered order. The snake starts on apple 1, and the glowing apple is always the next one to reach.
Fences block the way. A brown fence closes the path between two cells, so the snake has to find a way around it.
Fill every cell. Nothing crosses, no cell stays empty, and the snake finishes on the last apple.
Lost in the garden? The checkpoint button plants a golden flag on a cell your snake must pass through, extra direction without giving moves away, twice per puzzle. The hint button shows the wrong part of your snake in red, walks it back to the last correct cell, and reveals the next two cells. If you are already on track, it simply reveals the next three. You can also double tap any cell on the snake's body to slide back to it.
Tips from the garden
Corners first. A corner cell has only two ways in and out, so work out early how the snake will pass through it.
Don't strand cells. If a move would cut an empty region off from the rest of the garden, the puzzle is already lost. Slide back before going further.
Think a whole apple ahead. Before leaving one apple, sketch the route to the next one in your head, not cell by cell but as a shape.
Let the fences guide you. Every fence exists for a reason. If a fence blocks an obvious route, the solution wants you somewhere less obvious.
Questions
Is there only one solution?
Yes. Every Snakedoku board is generated and verified to have exactly one valid path. If you fill the garden, you found the path.
How many levels are there?
The journey starts on a friendly 4×4 garden and climbs toward expert 7×7 boards. After the main climb the levels keep coming, so there is always a next garden to fill. Your progress is saved on this device.
Do hints, checkpoints or undo cost anything?
No. They are always free to use, and your level progress is saved either way. Solving without them is simply extra bragging rights.
What do collected apples do?
Every apple your snake eats counts toward your daily total. Once in a while a sparkling golden apple appears and is worth five. Hitting a milestone lets you convert it into a Hungry Episode, which sprinkles five extra apples along your next level's route and makes it much easier to read.
Why do some levels feel easier than the one before?
That is on purpose. The difficulty rises in waves, so a tough garden is usually followed by a gentler one. You get a breather before the next climb.
