## What is Dinosaur Chain Puzzle?

Swap any two dinosaurs to match 3 or more — chain reactions blast your score sky-high!

"DinoKeshi Chain" is a swap-and-match puzzle played on a 5×7 grid. Tap any two dinos to swap them — no matter how far apart — then watch matches of 3 or more disappear in a chain-reaction explosion!

【How to play】
・ Tap any 2 dinosaur cells to swap positions (distance doesn't matter)
・ Match 3 or more of the same type to clear them
・ Cleared dinos fall, triggering chain reactions below
・ 2-chain = 2× score multiplier / 3-chain = 3× score multiplier!

【Strategy elements that keep it fresh】
 Skills
Match 5+ dinosaurs at once to fill your skill stock. Tap stored dinos on the left panel to unleash powerful special effects at just the right moment!

 Rock blocks
As you progress, rock blocks appear on the grid. Break them strategically to clear paths and maximize your chain potential.

## Version history (last 4 releases)

### 1.6.0 — 2026-07-10

We added a How to Play guide on the title screen, making the rules easier to understand for new players. A new Volcano block has been added: when its HP reaches 0, it explodes in a cross shape. Obstacles now appear randomly during refills, and their heart count increases as your level rises. The remaining moves display now blinks at 0 so it is easier to notice. Scores are larger to make big chains feel more rewarding. We also reviewed the App Store description and search keywords.
