HamiLoop vs Rulefold

HamiLoop: Draw one loop. Pass through every square on the grid exactly once. That's the whole idea behind HamiLoop, and it's harder than it sounds. What looks like a simple rule turns into a real puzzle once the grid grows, and figuring out the right path can take real thought. Grid sizes vary a lot, so difficulty varies with them. Some puzzles are solved in a couple of moments, others take much longer and require some careful planning. With 150,000 preloaded levels, you can pick a size and difficulty that suits your mood, and a new difficult puzzle is added every day if you're after something tougher. There are no timers and no countdowns anywhere in the app, so every puzzle can be worked through at your own pace. Each puzzle is presented with clean, colorful visuals, though the colors are purely decorative and don't affect the solving itself. If you like tackling more than one thing at a time, you can keep several levels open in parallel, so an easier puzzle is always there when you want a break from a harder one. Alongside the daily challenge, an extra hard puzzle is released once a week for players looking for something tougher still. The core idea of the game is inspired by Hamiltonian cycles, a well known concept from graph theory, giving the puzzle a solid mathematical foundation beneath its simple rule.

This is not Minesweeper. It borrows its numbers. The board is handed to you complete. Some cells show numbers; the mines are hidden. Nothing to click open, nothing to blow up, nothing to restart. You work out where every mine is. NO GUESSING. EVER. Every board is checked by a solver before it ships: if it cannot be finished by reasoning alone, it doesn't get in. When you are stuck, the information is already on the screen — you just haven't found it yet. FIVE RULES, NOT ONE • Classic — a number counts the mines around it • No Touch — no two mines may sit side by side • Liar — every number is off by exactly one • Far — numbers count a 5×5 area, not 3×3 • Odd/Even — clues tell you odd or even, never the count Then the rules start combining: Liar + No Touch, Far + Odd/Even, and more. 160 LEVELS, MEASURED NOT GUESSED Difficulty isn't a label someone typed in. It's the depth of reasoning a puzzle actually requires, measured by the same solver that verifies it. A NEW PUZZLE EVERY DAY, FOREVER Generated from the date, so everyone gets the same one. Keep a streak. Share your result without spoiling the puzzle for anyone. NEVER IN THE MIDDLE OF A PUZZLE Ads only between levels, never on the board. The daily puzzle has none. Free: all of Classic, the first half of No Touch, and the daily puzzle forever. Every other level unlocks with a short ad — or buy the full version once to open everything and remove ads.
