Hi Product Hunt! I’m jelkawasaki, the independent maker of 点と線パズル：5つのほどき方 (a Japanese title meaning “Dots and Lines Puzzle: Five Ways to Untangle”). Move dots, look for a new arrangement, and remove the crossings between lines. The game includes five modes and 250 puzzles, starting with exercises where just one point can move. You can undo a move, revisit a solved arrangement, and replay the steps you took. Larger dots, high-contrast settings, and tap-based selection offer alternatives to dragging. On iPad, the game uses the larger screen. You can also share a completed puzzle as an image or a short replay video. Please note: the app’s interface and instructions are currently in Japanese. An English version is planned. It is available on iPhone and iPad, and is free to play with ads. Removing ads is an optional one-time purchase; hints, undo, and replay do not require a purchase. I’d love to hear whether the basic interaction feels clear, and which of the five modes you enjoy most.
