Shooting Game Dominoes

Dominoes is a satisfying chain-reaction puzzle. Each level lays out a run of standing tiles, and you start the fun by dragging to aim a ball and releasing it to knock over the first domino. From there it's physics: that first tile falls into the next, which topples the one after it, and so on down the line until the required tiles are cleared. The catch is that gaps in the layout break the chain, and hitting too hard can scatter tiles instead of toppling them neatly, so a gentle, well-aimed shot usually beats a powerful one. The real thinking is spotting the 'keystone' — the tile whose fall triggers the longest cascade — and starting there.

- Aim: Drag to set the direction you'll launch the ball from.

- Launch: Release to send the ball into the first domino.

- Watch it fall: The chain topples tile by tile as each one knocks over the next.

- Clear the level: Topple all the required dominoes to advance.

- Look for the keystone tile — the one whose fall sets off the longest chain — and hit it first.

- A gentle, accurate launch usually beats a hard one — overshooting can scatter tiles instead of toppling them.

- Trace the collision path in your head before releasing, since a gap in the line breaks the cascade.

- On tricky layouts, target the cluster that branches out into the rest of the tiles.

- Mental: 55% — Working out which tile to hit to trigger the whole cascade is the heart of each level.

- Healing: 50% — There's something satisfying and low-stress about setting up a clean chain reaction.

- Reaction: 25% — You aim at your own pace — it's about the plan, not fast reflexes.
