Duplicados
Duplicados is a 2048-style puzzle game where you slide numbered tiles on a board to merge them. When two tiles with the same value collide, they combine into one with double the value (2 + 2 = 4, 4 + 4 = 8…). The goal varies by mode: in Classic you must reach the target tile (2048 and beyond), in Minimalist you have only 35 moves to reach 64, in Obstacles immovable walls divide the board complicating strategy, and in Chaos all special tiles appear at once — walls, damaged tiles and bombs that chain-explode. The game ends when no moves are possible.

Duplicados is a 2048-style puzzle game where you slide numbered tiles on a board to merge them. When two tiles with the same value collide, they combine into one with double the value (2 + 2 = 4, 4 + 4 = 8…).

The game ends when no moves are possible.
Game modes & special tiles
The game offers 5 board sizes (3×3, 4×4, 5×5, 6×6 and 8×8) combined with 4 active variants (Classic, Minimalist, Obstacles and Chaos), plus 7 additional modes in development (Time Trial, Zen, Reversed, Corrosion, Minefield, Fortress and Siege). Special tiles add depth: obstacle tiles 🧱 are immovable walls that divide rows and columns, damaged tiles 💔 temporarily block merges until they expire, and bomb tiles 💣 chain-detonate when paired, clearing entire lines.
Power-ups & achievements
Three unlockable power-ups available through rewarded ads help in critical moments: Undo (revert to previous state, up to 3 times per game + extra undos), Remove Tile (remove a problematic tile from the board, 1 use per game), and Swap Tiles (swap the position of two tiles, 1 use per game). An achievement system with over 100 medals rewards scoring milestones (1K, 5K, 10K), tile progression (256 → 131072), accumulated wins, and special challenges like the Purist — winning without using any power-up.
The experience
Duplicados offers quick mental puzzle sessions that scale in difficulty. On small boards (3×3, 4×4) every swipe counts and games last minutes; on large boards (6×6, 8×8) with special tiles, strategic complexity grows exponentially. The game aims for that addictive 'one more game' feeling of classic 2048, but with much more variety and replayability thanks to the modes, dynamic obstacles and the achievement system that always gives you a new goal.
