The climb: green teaches the moves, blue plays numeral AND sport at once, the black diamond is a pure icon sudoku, and the double black diamond is the summit — two full sudokus in every tile.
How to play — Fresh Tracks
Every tile is two puzzles at once — the numeral and the sport both have to fit. Pick a card below, then tap where it goes.
Green: the bunny slope — I, II, III and IV in four different suits. Every card fits anywhere; just learn to pick up and place. The rules kick in on blue.
Blue: 4×4 — every row, column and 2×2 box needs each numeral I–IV and each sport once.
Black diamond: 9×9, icons only — every row, column and 3×3 box needs all nine winter sports. Big clean tiles, one constraint, real sudoku depth.
Double black: the true summit — 9×9 where numerals I–IX AND nine sports are both sudoku-valid at once. Two puzzles in every tile.
The lineup is exactly the right cards to finish the board, and you never have to guess — guaranteed. From the first tile to the last, there is always a cell that accepts exactly one of your cards, or a card with only one home. Start where a row, column or box is fullest, and if you can’t see it, 💡 will.
A move that breaks the rules — or would make the mountain impossible to finish — gets an ✗, but the card comes back to you to try somewhere else. Mistakes add up: three ✗ in one run and you’re out. Every deal is solvable.
💡 is your coach — it glows a correct card and spot when you’re stuck — and costs one ✗.
Your game saves itself — close the app, come back, keep climbing.
How to play — Avalanche
The goal is survival: the run ends when the mountain fills to the top. Merging keeps it clear — and scores.
Tap a ▼ lane (or anywhere in a column) to drop the tile there before the clock drops it for you somewhere random.
Touching tiles with equal numerals merge upward: I+I→II … IX+IX→X. Two X’s vanish in a 💥 for a big bonus.
Same-sport merges score double, and every point is multiplied by your level.
Every 15 drops = next level — the clock gets a little faster. Keep the rhythm.
