Xmas Snow Challenge - Maze Puzzle

So you''re Chris, Santa''s helper, and every level is a square grid of snow tiles. Your thumb swipes left, right, up, or down--Chris slides in a straight line until he hits a wall or an obstacle. The goal? Slide over every single snow tile on the field. Miss one and you can''t finish. It''s that simple at first, but the game sneaks in complications. Early levels like "Frosty Field" or "Gingerbread Grove" are open, maybe a few walls, and you can brute-force it by trial and error. But by world two, you hit "Icicle Alley" and there are rocky obstacles--little grey boulders that block your path. Run into one and Chris stops, which usually means you''re stuck and have to restart. The restart button is a tiny snowflake icon top right, and you''ll tap it a lot. What makes it click is the portal mechanic. Green and blue portals appear around level five. Step onto one and you teleport to its matching pair on the other side of the maze. This lets you cover split sections without backtracking through the whole grid. Later, around "Crystal Caverns," red portals show up that only work one way. You have to plan your route or you''ll paint yourself into a corner. The satisfying moment is when you clear the last tile and all the snow vanishes with a little sparkle sound, and the level name pops up with a star rating. Three stars if you didn''t use any hints. The hint booster is a magnifying glass icon--tap it and a ghost trail shows the next few moves. It costs in-game coins from clearing levels. The magic wand booster removes one obstacle, like a boulder or even a portal, which is handy when you''re one tile short but blocked by a rock you didn''t plan for. Both boosters refill slowly or you can watch an ad. Difficulty ramps unevenly. Some levels are two-minute slogs with fifteen portals and a dozen rocks. Others are tiny four-by-four grids that still take three restarts because of a sneaky corner. There''s no lives system, so you can replay as much as you want. The brain work is forward planning--you have to visualize the path before swiping, because once you commit, there''s no undo. Hands just swipe, sometimes fast when you''re confident, sometimes slow and hesitant when you''re counting tiles. The game never tells you the optimal path; you figure it out by getting stuck and learning. That''s the loop: swipe, get stuck, restart, swipe smarter. Not much else to it, but the good kind of simple.
