Onespark (Dayzle)
Rate itAdd just enough bombs that one spark sets off the whole board, without a blast reaching a vase.
Every day: One chain-reaction board a day, the same for every player: bombs with cross, diagonal or full blasts, red crates that fire in a line, walls, and from Wednesday porcelain vases, plus a par of extra bombs. Monday and Tuesday are 6x6 with 2 groups, Wednesday to Friday 7x7 with 3 groups, the weekend 8x8 with 4. New puzzle: Midnight, local time.

Onespark is a daily chain-reaction puzzle on Dayzle. Cartoon bombs sit on a plank floor in separate groups, each bomb with its own blast shape; you drop a few extra bombs so that one spark sets off every bomb on the board, using as few extras as par and breaking no vases.
About Onespark (Dayzle)
Onespark is one of the eighteen daily games on Dayzle, a site of original puzzles from TLL Studios in Valencia. Each day at local midnight it sets one board, the same for everyone.
The board is a square plank floor holding black bombs and red crates. A bomb marked + hits the four squares beside it, one marked with a cross hits the four corners, and a starburst hits all eight around it. A red crate fires in a straight line where its arrow points, through bombs and vases, until a wall or the edge. Any bomb caught in a blast goes off too, so one spark can run down a whole chain. Walls stop crate blasts but not the others.
The bombs start in separate groups that cannot reach each other. You drag extra bombs from a tray onto empty squares to bridge them, then tap Spark and choose which bomb to light. From Wednesday one or two porcelain vases appear; if a blast reaches one the chain stops with a crash and the try fails. Holding any bomb shows the squares it would hit.
Par is the fewest extra bombs possible: matching it gives three stars, one more gives two, anything else one. Tries are counted but cost nothing, and the board comes back after each with your extras in place. The week grows from 6x6 with two groups on Monday to 8x8 with four at the weekend.
The shared result shows the extras you used against par, your number of sparks and one burst per explosion of the winning chain. Past editions stay open for practice and never count.
How to play Onespark (Dayzle)
- Look at today's Onespark board and its par of extra bombs; press and hold a bomb to see the squares its blast hits.
- Drag extra bombs from the tray onto empty plank squares so each group's blast can reach the next group.
- Tap Spark, then the bomb to light, and watch the chain; bombs that wobble did not go off.
- Move or remove extras and spark again until every bomb goes off and no vase breaks, then share your result.

Tips
- Count the gaps between groups first: you usually need one extra bomb per gap, which is a good guess at par.
- A crate fires one way only, so trace each group back to the bomb that must start it and aim your extra at that one.
- Next to a vase, a cross or diagonal bomb often slips between the vase and a bomb where a starburst would break it.
- Tries are free: place, spark, see where the chain stops and adjust.
Questions
When does the Onespark board change?
At midnight in your own time zone. Everyone gets the same board that day.
Do failed sparks cost stars?
No. Stars depend only on how many extra bombs you used against par; the number of tries is shown but not scored.
What breaks a vase?
Any blast that reaches its square, including a crate's line blast. A broken vase stops the chain and that try fails.
Is Onespark free?
Yes. It plays in the browser with no account, and past days are free to play for practice.
