RULES:

The game is played on a grid of squares, each of which is red, green or blue, and each of which can be controlled by either player or nobody. They all start off uncontrolled. At the end of the game, the player who controls the most squares is the winner.

Each player's turn consists of three parts: take control of an uncontrolled square, ping a square they control, and then deal with any chain reaction.

1. Take control of an uncontrolled square: Just click a square that has no controller (no black or white border).
2. Ping a square you control: You choose a square you control, and "ping" it, which does two things. First, it changes its colour to a colour of your choice (which could be the colour it was already). Then, the squares around it are checked to see if they have been captured. The rules for capturing a square vary between rulesets (see Rules Variations), but in all cases: If the pinged square has turned red, any adjacent green squares may be captured, if there are additional red squares also surrounding that green square. If the square is pinged green then adjacent blue squares may be captured, and if the square has pinged to blue then adjacent reds may be captured. If a square is captured, then it comes under your control (no matter who controlled it before), and itself pings. This can in turn capture and ping more squares, leading to impressive chain reactions and giving you control of several squares in one turn.

Rules Variations

Two rulesets are particularly interesting, named Ruleset 1 and Ruleset 3.

In Speed Sparklies, a pinged square which has turned red will capture any adjacent green square which has at least one other red square around it. In other words, if a green square is surrounded by at least two red squares, one of which has just pinged, then the green square will be captured and ping.

When it pings, it will turn red, and potentially capture further green squares.

In Subtle Sparklies, a pinged square which has turned red will capture any adjacent green square which has at least one other red square owned by the capturer around it. In other words, if you own at least two red squares adjacent to a green square, one of which has just pinged, then the green square will be captured and ping.

When it pings, it will turn to the colour of the capturer's choice, and potentially capture further squares.
