Burst Chain

Take turns adding orbs to a small grid against the computer. Fill a cell to its limit and it bursts, spreading to its neighbours and stealing them.

How to play

  1. On your turn, add one orb to an empty cell or to a cell you already own.
  2. Corners hold up to 1 orb and burst on the second, edges burst on the third, and the middle cells burst on the fourth.
  3. A burst sends one orb to each neighbouring cell and turns those cells to your colour, which can set off more bursts.
  4. Wipe out every opposing orb after both sides have moved to win. Pick Easy, Normal or Hard for the computer.

Tips and strategy

  • Corners are cheap to fill and quick to burst, which makes them good chain starters early on.
  • A gold border means one more orb bursts that cell. Check where the computer can do that before you move.
  • Do not leave your cells next to an almost-full red cell. A single burst will flip them.
  • Long chains can swing the whole board, so look for a move that sets one off rather than just growing your count.

FAQ

Can I place on the computer's cells?
No. You can only add to empty cells or your own cells. Bursting is how you take theirs.
When does the game end?
As soon as one player has no orbs left after both sides have played at least once.
How smart is Hard?
Hard looks one reply ahead and avoids moves that let you win a chain. It is beatable, but it punishes careless setups.
