Gem Cascade
About Gem Cascade
Gem Cascade is our own match-three, built as a sixty-second sprint rather than a level grind. Swap two neighbouring gems to line up three or more, and watch what falls into the gap. Chains that keep resolving score more than the match that started them, so the board you leave behind matters as much as the match you make.
How to play
Tap a gem, then tap a neighbour to swap them. Line up three or more of a kind to clear them. New gems fall in from the top, and if they make another match it cascades for extra points. You have sixty seconds.
Rules of Gem Cascade
- The board is eight columns by eight rows, and it sits low on the screen so your thumb reaches the far corners.
- Six gem types are in play: a green triangle, a red circle, an amber square, a blue diamond, a purple hexagon and a pink star.
- Only gems sharing an edge can trade places. Diagonal swaps are not a move.
- Line up four or more and all of them go, not just the first three.
- A run lasts sixty seconds and nothing extends it, so the clock is the only thing that ends a game.
- Replacements drop from the top of the column, so the gap you open gets filled by whatever was sitting above it.
- Gems that fall into a gap and land in a match clear on their own, and each further resolve in that chain is worth more than the one before it.
Controls
- Tap a gem to select it
- Tap an adjacent gem to swap the two
- Tap the selected gem again to deselect
What makes it worth playing
- A sixty-second run, so a game fits in a queue or a lift
- Cascades multiply, rewarding setups over single matches
- Every gem type has its own shape as well as its own colour
- The board is checked after every resolve and reshuffled if no move exists
- Starts from a board with no free matches already on it
- No assets to download, so it starts instantly

Tips from playing it
- Match low on the board whenever you can. Everything above it has to fall, and falling gems are what start cascades.
- A match at the top clears three gems and ends. The same match at the bottom can clear ten.
- With ten seconds left, stop hunting for the perfect cascade and take every match you can see.
- Watch the shapes rather than the colours once you speed up. They read faster at a glance.
Notes from building it
Two rules in this game exist because of how match-three usually fails. The first is that the board can never be dead. After every single resolve the game asks whether any swap on the board would produce a match, and if the answer is no it reshuffles rather than letting you stare at a board with no moves while the clock runs. The starting board is generated the same way: it is rejected and redrawn until it contains no free matches and at least one real move. The second is that every gem type has a distinct shape, not just a distinct colour. About one man in twelve has some form of colour vision deficiency, and a match-three that encodes its only information in hue is a poor game for them. The shapes cost nothing and the game reads faster for everybody at speed.
