What is Klyvex
Klyvex drops shards down an eleven-wide well, but the shards are not all the same size and the clearing is not all about rows. Each one carries a size — three, four or five squares — and one of four prism colors. Land five or more blocks of the same color touching each other and they shatter on the spot, whatever shape they came in. Everything above drops into the hole, and if the drop makes another group of five, that shatters too. Chains are where the score lives.
A full row still clears, and pays well when it happens, but with shards this size a complete row is a small event rather than the point of the game. The point is color: reading which of the four is spreading, steering the next three shards toward it, and setting up a collapse that keeps collapsing. On top of that there is the shift meter, which charges as you clear and lets you slide every landed row one cell sideways with the edges wrapping around — the one move that can rescue a stack you have painted into a corner.
How to play
- Arrow keys move and soft-drop, up or X rotates one way, Z the other, space is a hard drop and C holds a shard for later. On a phone the buttons under the well do the same. The dashed outline shows exactly where the shard will land.
- Five or more blocks of one color, touching side to side or top to bottom, shatter the moment a shard locks. Diagonals do not count. Each shattered block pays forty points times the chain times your level, so a group of nine in a chain of three is worth far more than three separate groups of five.
- A full row clears for two hundred and sixty points and up, times level and chain — one row is rare with shards this size, and two at once is a real achievement. Clearing rows is also the fastest way to charge the shift meter: thirty per row against four per shattered block.
- With the meter full, A and D slide every landed row one cell left or right; blocks pushed past the edge come back on the other side. Use it when one color is stranded on the wrong side of the well. From level five the cinder tide starts pushing burnt rows up from below — those never shatter, and every one of them steals a row of breathing room.
Strategies that work
- Do not chase rows. A line-first player and a color-first player were measured over two hundred shards each: the color player scored about ten per cent more while completing a fifth as many rows. Rows are a bonus that turns up while you are building color, not a plan.
- Keep one color deliberately thin. Four blocks of a color sitting apart are dead weight — they cannot shatter and they cannot be cleared except by a row. When a color is not going anywhere, stop feeding it and let the next shard of that color go somewhere it can join the others.
- The single square and the domino are the whole reason the shift meter matters. They are the rarest shards in the bag and the only ones that reliably plug a one-cell hole, so when one arrives, spend it on the hole that is blocking a group of four from becoming five.
- Chains are worth more than size. The multiplier climbs with each collapse in the same cascade, and it multiplies rows and shatters alike — so a nine-block group that triggers two more groups underneath pays more than a fifteen-block group that ends the cascade. Build the second collapse before you set off the first.
- Save the shift for the cinder tide. From level five a burnt row rises every twelve to twenty-seven seconds, and burnt blocks never shatter — the only way to remove them is to complete a row that includes them. A shift at the right moment lines the gaps in two burnt rows up with each other and turns a slow burial into one clean row.
A little history
The falling-block puzzle has two ancestral branches. One clears full rows; the other clears groups of matching colors, and its descendants — the ones where a collapse triggers the next collapse — turned the genre from a test of packing into a test of planning. Klyvex sits on the second branch and takes the first only as a bonus: rows still clear, but a color group of five is the everyday event and the chain is where a run is won or lost. The shard set is the other departure. Rather than a fixed family of four-square pieces, Klyvex deals shards of one to five squares, weighted so the small ones are rare enough to matter — the single square is the least common shard in the bag, and it is the one that plugs the hole that turns four blocks into five. The grid shift, which slides every landed row sideways with the edges wrapping, has no ancestor in either branch: it exists because a color game punishes you for having the right color on the wrong side of the well, and one move that fixes that is more interesting than a well you can never recover.
Frequently asked questions
Do the rules change on the daily challenge?
No — the rules are identical. What the date fixes is the sequence: everyone on Earth gets the same shards in the same order with the same colors, and the same gaps in the cinder rows. It comes from the date in UTC, so it turns over at the same instant everywhere and does not read your computer's clock. Outside the daily, the shards are drawn at random and every run is different.
Why do rows clear so rarely?
Because the shards are bigger than the classic four squares and the well is eleven wide, so packing a row flush is genuinely hard — and because every color shatter punches holes in what you had built. That is the trade: the game gives you a second, easier way to clear that fires many times per minute, and in exchange the row becomes a rare, well-paid event. A player going out of their way for rows manages about fifteen in two hundred shards.
What happens when the cinder tide reaches the top?
The run ends. From level five a burnt row pushes up from below every twelve to twenty-seven seconds — faster at higher levels — and the warning strip flashes about two and a half seconds before each one. Burnt blocks are grey, they belong to no color, and they never shatter: the only way to be rid of them is to complete a row that contains them. Each rising row also pushes the shard you are holding up with it, so a stack near the ceiling can end a run in a single tide.
