↔
Shift neighboring symbols
Exchange two adjacent pieces and reshape the grid. Each swap should create value now or prepare a stronger reaction later.
Match reaction system
Swap. React.
Gabbro Reactor turns a colorful grid into a chain of tactical decisions. Exchange neighboring symbols, create matches, trigger cascades and complete each objective before your available moves reach zero.

REACTION 03 / COLLECT REQUIRED SYMBOLS
01 / Reactor logic
One swap can change the entire field.
Gabbro Reactor rewards more than immediate matches. Strong moves can prepare new alignments, trigger falling pieces and begin chain reactions that solve several objectives at once.
3+
Form matching lines
Align three or more identical symbols horizontally or vertically to remove them from the board and advance your target.
↓
Trigger cascades
Cleared pieces create empty spaces. New symbols fall into place and can automatically produce additional matches without another move.
◎
Complete the mission
Collect the requested pieces, remove obstacles or reach the required score before your remaining move count reaches zero.
02 / Reaction components
Different systems. One connected board.
Every mechanic is designed to interact with the grid, encouraging players to look beyond a single match and think about what the board can become.
COMPONENT A
◆
Colorful symbols
Distinct shapes and colors make the board easy to scan while giving every reaction clear visual feedback.
COMPONENT B
⚡
Power pieces
Larger matches can produce special elements capable of clearing rows, columns or wider areas of the grid.
COMPONENT C
∞
Changing objectives
New stages can introduce collection goals, barriers, special tiles and different board conditions.
COMPONENT D
◉
Tactical move limits
A fixed number of swaps gives every level strategic pressure and makes inefficient decisions matter.
03 / Reaction cycle
Four stages between a static grid and a chain reaction.
01
Scan the field
Check the objective, available moves and current symbol arrangement before committing to your first swap.
02
Swap adjacent pieces
Move one symbol into a neighboring position to create a line of at least three identical pieces.
03
Let the reaction spread
Cleared symbols allow new pieces to fall. Watch for automatic secondary matches and opportunities to build a larger combo.
04
Finish the objective
Continue building useful reactions until the level goal is complete or your available moves are exhausted.
Simple interaction.
Complex consequences.
Gabbro Reactor is easy to understand because every action begins with a simple swap. The depth comes from predicting the result: what disappears, what falls, which new match becomes possible and how many objectives one reaction can complete.
Swap • Match • Cascade • Complete
04 / Reactor questions
Before the next reaction.
The core rules remain straightforward, but learning how matches, cascades and move limits interact is what turns simple play into stronger strategy.
What type of game is Gabbro Reactor?
Gabbro Reactor is a swap-and-match puzzle where neighboring symbols are exchanged to create groups of three or more identical pieces.
What is a cascade?
A cascade happens when one completed match causes pieces to fall and automatically creates another valid match without requiring an additional swap.
Are there special power-ups?
Yes. Larger matches can create special pieces that help clear wider areas, rows, columns or difficult sections of the board.
Do levels use different objectives?
Yes. Individual stages can focus on collecting specific symbols, clearing obstacles or reaching a target result within the available moves.
Can Gabbro Reactor be played offline?
Core puzzle levels can support offline play, while online features such as leaderboards or events may require an internet connection.
