Start the Chain Reaction
Fission is a logic puzzle game built around one simple idea. A group of lettered circles appears on the screen, and the goal is to clear every circle with one carefully chosen move. Players select a circle and release the small dots around it. Those dots travel in straight lines and can hit nearby circles. When another circle gets hit, it bursts and sends out its own dots. This creates a chain reaction that can spread across the whole level.
The challenge comes from finding the correct starting circle. A random click does not always clear the board. Players need to study the positions of the circles and notice the direction of the dots before making a move. One good choice can set off a reaction that reaches every target.
How the Circles Work
Each circle can have between one and four small dots around its edge. The position of those dots decides the direction in which they travel. A dot can move horizontally, vertically, or diagonally. This gives each circle a different role in the chain reaction.
When a released dot touches another large circle, that circle pops and sends its own dots toward other circles. The reaction continues as more circles connect with one another. The player needs to plan the first move carefully because the level depends on the full sequence that follows.
The letter inside each circle helps the board look clear and organized. The simple design also makes it easier to focus on the positions of the circles rather than extra decorations.
Later Levels Add More Thinking
Fission contains 30 levels, and the stages become more involved as the game moves forward. Early levels teach the basic chain reaction idea. Later stages introduce circles that players can move into different positions before starting the reaction.
Moving these circles becomes an important part of the puzzle. Their final positions can decide whether the released dots reach the right targets. Players need to place the movable circles carefully and then find the circle that should start the reaction.
This gives the game two types of decisions. First, players need to arrange the board when movement is available. Next, they need to choose the correct circle to pop. Both steps work together.
Simple Controls
The controls in Fission stay easy. On a computer, the player uses the mouse to select a large circle. Touchscreen devices can use a tap instead. A reset option lets the player restore the level and try another approach. There are also buttons for sound and returning to the home screen.
The simple controls make the puzzle suitable for players who enjoy games that depend more on observation than fast reactions. There is no complicated movement system to learn. Most of the work happens in the player’s head while studying the board.
Look for the Perfect First Move
A useful way to play Fission is to examine every circle before making the first move. Players can check where each dot points and think about which circles could be reached after the first burst. A circle near the center may affect several others, while a circle near an edge may have fewer useful connections.
The puzzle also rewards patience. Players can take a moment to inspect the board instead of clicking immediately. When a reaction fails, the reset button makes it easy to try another starting point or adjust movable circles in later stages.
A Puzzle About Timing and Position
Fission keeps its main idea focused on chain reactions, but the 30 levels give that idea plenty of room to develop. The early stages introduce the basic rules, while later puzzles use positioning to make the solution less obvious. Each successful level comes from finding the right sequence rather than relying on speed.
With simple controls, clear rules, movable circles in later stages, and a strong focus on planning, Fission offers a thoughtful puzzle experience. The game asks players to watch the board closely, predict where the dots will travel, and choose the one move that can start a complete chain reaction.
