RuneSurf

RuneSurf is a 2048-style number puzzle with a campaign behind it. Swipe and every carved stone on the board slides the same way. Two stones carrying the same number fuse into their double. That is the whole language — and then 48 hand-tuned tides make you use it properly. WHAT MAKES IT A CAMPAIGN, NOT JUST A GRID Each tide opens with a board already part-carved and names one target stone to reach before the move counter runs out. Later water grows coral through the grid, splitting lanes and forcing you to work around it. Four worlds — Tide Shallows, Glass Reef, Deep Trench and Rune Crest — go from open 4x4 water to tight 5x5 boards with the least starting stone and the sharpest pars. Every tide is solvable inside its own move limit. Clearing one is the easy part; clearing it in few enough moves for three stars is the game. ENDLESS SURF No target, no move limit, no ceiling. Just you, a 4x4 board and how far the numbers will go. Your best score and biggest stone are kept on the Standing sheet. FOUR CHARMS FOR WHEN THE BOARD TURNS Foresight lights the strongest swipe available. Rewind pulls the tide back one move. Shatter breaks a single stone off the board. Ward sweeps away every stone of the lowest value at once. THE CARVING FORGE Runes earned from tides, the daily gift and Endless runs buy permanent upgrades across four tracks: richer payouts, free Rewind charges at the start of every tide, extra moves on every board, and bonus stones already carved when the tide opens. Four tiers each, and everything is earned by playing. ALSO IN THERE A Rune Codex that writes a page for every stone value you reach. Fourteen honours mapped to the campaign's own progress — no separate busywork ladder. A daily gift that resets at midnight. A bookmark that resumes an interrupted tide exactly where it stopped. BUILT TO BE LEFT ALONE WITH Completely offline. Airplane mode changes nothing. No account, no sign-in, no email address. No ads. No in-app purchases. Nothing to buy at any price. Clear marks mode adds a tick per doubling to every stone, so value reads by count as well as by colour. Calm light stills the drifting motes and the glow. Three swipe sensitivities, because thumbs differ. Your progress lives on your device and nowhere else.
