Gem Match-3

How to play Gem Match-3

Gem Match-3 is AppFreeGame's original take on the classic tile-swap puzzle, played on an 8x8 board of coloured gems. The idea is simple to learn and hard to master: swap two gems that sit next to each other so that three or more of the same colour line up in a row or column, and that line clears. Clear a line and the gems above it tumble down to fill the gap while fresh gems drop in from the top — and if that fall happens to create ANOTHER line on its own, it clears too, kicking off a cascade that can chain several times from a single swap. Every game gives you exactly 30 moves, so each swap matters: the best players are not just looking for any match, they are looking for the swap that sets up the biggest chain.

The goal

Score as many points as you can before your 30 moves run out. There is no separate "win" condition beyond that — every swap that creates a match adds to your score, and cascades multiply your reward, so the goal is simply to plan swaps that clear the most gems, in the longest chains, using the fewest moves. Scores are capped at 99,999, which is far more than any single round is likely to reach, so you never have to worry about the number overflowing.

Difficulty and gem colours

The three difficulties change only one thing, but it matters a lot: how many different gem colours are in play. Easy uses 5 colours, Medium uses 6, and Hard uses 7. Fewer colours mean matches are easier to spot and cascades happen more often almost by accident; more colours spread the board thinner, so you have to hunt harder for a good swap and cascades become something you have to plan for deliberately rather than stumble into. The board is always 8x8 and the round is always 30 moves, no matter which difficulty you choose — only the palette changes.

Controls

• Tap or click a gem, then an adjacent gem — the two swap places. If the swap creates a match it resolves immediately; if it does not, the gems bounce back into place and nothing is spent.
• Arrow keys move a keyboard cursor — press Enter or Space to select the gem under the cursor, move to a neighbouring gem, then press Enter or Space again to attempt the swap.
• Touch, mouse and keyboard all work — there is no drag gesture required; a simple tap-then-tap (or select-then-select) is all any move takes, which keeps the game equally comfortable on a phone or a desktop.

The rules

• The board is 8 columns by 8 rows of coloured gems. You may only swap two gems that are orthogonally adjacent — directly beside each other horizontally or vertically. Diagonal swaps are not allowed.
• A swap is only legal if it creates a line of 3 or more identical gems in a single row or a single column. The game checks this the instant you release the swap.
• If the swap you attempt would NOT create a match, it is rejected: the gems visibly bounce back to where they started, no move is spent, and your score is untouched. Feel free to explore — an illegal attempt costs nothing.
• When a match clears, every matched gem disappears, the gems sitting above each cleared cell fall straight down to fill the gap (gravity), and brand-new gems drop in from the top of each column to fill whatever is left empty.
• Because new gems keep arriving from the top, the board is re-checked after every fall. If the new arrangement happens to line up another 3-or-more match on its own — with no extra swap from you — that match clears too, and the board falls and refills again. This is a cascade, and each successive step in the same chain scores at a higher multiplier (the first clear is worth 1x, the next 2x, the one after that 3x, and so on), so long cascades are dramatically more valuable than the same number of gems cleared one swap at a time.
• A fresh board never starts with an accidental match already on it, and the game guarantees there is always at least one legal swap available. If a cascade or a run of swaps ever leaves the board with genuinely no legal move anywhere, it is automatically reshuffled — the same gems are re-arranged in place, nothing is added or removed — and a short on-screen notice lets you know it happened.

Scoring

• A line of exactly 3 gems is worth 30 points. A line of 4 is worth 60. A line of 5 or more is worth 150 — going for longer lines pays off disproportionately.
• If your swap creates more than one line at once (an L or T shape touches two lines simultaneously), both lines score in that same step. Look for these shapes; they are one of the fastest ways to rack up points from a single swap.
• Every cascade step after the first is worth more: the first clear from a swap scores at 1x, the second (gravity-triggered) clear in the same chain scores at 2x, the third at 3x, and so on for as long as the chain keeps going. A modest match that kicks off a 3-step cascade can easily out-score a single huge line.

Strategy tips

• Scan for cascades before you swap. Before committing to the first match you spot, check whether a different nearby swap would leave the board set up for a chain reaction once gravity kicks in. A move that triggers a 3-step cascade is worth far more than three separate single matches.
• Chase length over quantity. A single line of 5 (150 points) beats a line of 3 (30 points) five times over even though it only uses two more gems. If you can choose between an easy 3-match and a slightly trickier 4- or 5-match, take the longer line.
• Hunt for L and T shapes. A swap that completes two lines of 3 at once (crossing in an L or T) scores both lines in the same step — effectively double value from one move. These shapes are easy to miss if you only look at one row or column at a time.
• Budget your 30 moves. With a hard limit on moves, an "okay" swap that clears a line right now is sometimes worse than a "wait one move" swap that sets up a much bigger cascade next turn. In the closing moves of a round, prioritise whichever swap you are certain will land, since there is no time left to recover from a wasted attempt.
• Do not fear a reshuffle. If the board genuinely runs out of legal moves it reshuffles automatically and keeps every gem you had — you lose no progress and no score. Treat it as a free reset of the board layout, not a penalty.
