Laststone

Laststone is a portrait, single-finger tactical puzzle inspired by the readable geometry and suspense of curling. Drag to set a line, choose left curl, straight, or right curl, and sweep along the glowing lane to shape the final distance. Every short match takes about two to four minutes. Eight handcrafted levels turn guards, draws, takeouts, setup stones, counter-lines, and the decisive last stone into compact original puzzles rather than repeating the same target with larger numbers.

The campaign starts with a clear first sweep, then introduces protected lanes, collision angles, persistent setup stones, opponent pressure, and a three-stage Club Final. Preview markers show the target, route, expected landing area, danger direction, and sweep influence before a result is committed. Immediate visual and audio feedback explains whether a shot was short, long, wide, or affected by a collision, so every retry has a useful purpose.

A failed attempt does not erase a confirmed good stone. Completed stones remain in the house while a responsibility arrow and distance metrics explain the next adjustment. Successful shots are preserved in the Shot Book with the final house, ghost route, rules version, landing accuracy, effective sweep, and whether the shooter stayed in play. Completed levels also light the trophy wall in the Club Lounge, giving every brief session a lasting record and a visible sense of achievement.

Laststone supports portrait play with one finger, mute settings, and reduced-motion presentation. Muted play keeps equivalent color, text, and shape feedback, while reduced motion preserves the same decisions and result information. There is no forced energy system. Interstitial ads are limited to appropriate low-frequency transitions, and rewarded ads only offer optional presentation or collection benefits. Advertising can never alter stone positions, scoring, completion, or mastery results.

This is a curling-inspired tactical puzzle, not an official competition simulation, officiating tool, or training product. It does not claim to reproduce every formal rule, and it does not use real events, teams, athletes, trophies, sponsors, or third-party trademarks.
