PhysicsDrop MergePro

One Move Changes is two merge puzzles in one app, each built on its own rule. In Nova Drop, numbered spheres fall into a tube with real physics. They fuse when their numbers are neighbours on the Fibonacci ladder — 1 joins 2, 2 joins 3, 3 joins 5 — not when they match. In Chain Forge, you trace a path through three or more tiles of the same value and collapse the whole chain into the next power of three. Both boards are rendered in 3D. Everything runs on your device: no ads, no in-app purchases, no accounts, and no internet connection required. Feature: • Two games with separate rules, ladders and boards
• 3D boards, with physics simulation in Nova Drop
• Four modes: Classic, Timed, Puzzle and Daily Challenge
• 60 puzzle levels with move limits and up to three stars each
• A daily challenge generated from the date, so it works offline
• Four power-ups earned through play: Undo, Hammer, Shuffle, Freeze
• 22 achievements and 5 unlockable board themes
• Daily streaks, with streak freezes for missed days
• Stats dashboard and run history, with past boards viewable in 3D
• Runs are saved automatically if you leave mid-game
• Three grid sizes for Chain Forge: 4×6, 5×7 and 6×8
• Portrait orientation, one-handed play How to play: Nova Drop — Aim, then release to drop a sphere. Two spheres fuse when their values sit next to each other on the ladder. Fuse again quickly to raise your multiplier. Keep the pile below the red line. Chain Forge — Drag through three or more touching tiles of the same value, then release to forge the next power of three. Chain six or more to overforge. Tiles fall to fill the gaps, and new groups formed by the fall score a cascade. Benefits: • Two different pacings — one reactive, one deliberate
• Sessions from 90 seconds to as long as you want
• All power-ups are earned by playing; there is nothing to buy
• No accounts, no analytics and no tracking — the app makes no network requests
• Works fully offline, daily challenge included
• Progress, statistics and past runs are kept and reviewable
