ORBGRID : chain reaction

ORBGRID is a chain-reaction strategy game. The rules take ten seconds to learn. Seeing three moves ahead takes considerably longer.

HOW IT WORKS
Tap a cell to drop an orb into it. Every cell has a limit — four in the middle of the board, three along an edge, two in a corner. Push a cell past its limit and it bursts, sending one orb into each neighbouring cell and claiming them for you. Those cells can burst in turn. One tap can cascade across the entire board and reverse a losing position in a second.

MODES
• Solo vs CPU — four difficulty levels, from Easy to an Expert that searches several moves deep. Your opponents have names, you pick your own colour, and your last difficulty is remembered.
• Pass & Play — 2, 3 or 4 players on a single device, no second phone required.
• Daily Challenge — a new puzzle every day: reach the objective within a move limit. No timer, so think as long as you like. Keep your streak alive.
• Tutorial — a guided match that teaches capacity, explosions and cascades while you play.

TOOLS FOR THINKING AHEAD
Cells about to burst are highlighted, so you can see the danger before you commit. Press and hold any cell to preview the full chain reaction your move would trigger — the whole cascade, resolved, before you lift your finger. Every match ends on a statistics screen: peak control, cells captured, the biggest chain reaction, who eliminated whom.

STONING MODE
Let a match run long enough and the board starts sealing itself, cell by cell, until there is nowhere left to hide. No match drags on forever.
