Slither Link Plus is a type of mathematical logic puzzle composed of a grid and numbers placed inside it. Based on the numerical clues, players must draw a single, continuous, closed loop along the edges of the grid.
On a grid of dots, connect adjacent dots with directional lines to form a closed loop.
A number in a cell indicates how many of its surrounding edges should be part of the loop. Empty cells may have any number of surrounding lines.
The loop must not intersect, branch, or split, and only one loop is allowed on the board.
In addition to the classic square grid, this version also includes hexagonal, kite-shaped, and Cairo tiling boards — each offering unique logic patterns and solving strategies.
Includes 5 board types and over 250 + N handcrafted levels, suitable for players of all skill levels — from beginners to puzzle masters.
Multiple color themes are available to customize your visual experience.
Achievements system lets you unlock rewards by completing in-game levels.
A built-in level generator supports all board types and three difficulty settings, providing infinite randomly generated puzzles for endless play anytime.
When you are certain that a line should be placed at a certain position, left-click on that position to place the line. When you are sure that no line should be placed at a certain position, right-click on that position to mark it as having no line.
If you are unsure about what to do next during the game, you can click on the magnifying glass icon to use the hint function and get guidance for the next move.
If the hint function doesn't help solve the problem, you can use the assumption function. First, place a line, and then click the flag button. This action will bookmark the previous operation of placing the line. Then continue with the game. If you later find that you can't proceed further, you can long-press the undo button for 2 seconds to directly undo to the bookmarked position, thus eliminating the invalid operation you just made.
