Double It

Somewhere in deep space, numbers became liquid. Nobody knows why. Your job is to merge them.

DOUBLE IT is a number-merging arcade puzzle where every number is a droplet of living light they drift, wobble, reach for each other and fuse like tiny romantic comets. Match equal numbers to double them, keep the orbital ring from overflowing, and chain reactions until the whole board sings.

Then math shows up. Not the school kind the cool kind. The constants of mathematics φ, π, e, Σ and ∞ are your superpowers.

FOUR WAYS TO PLAY
• CLASSIC — the full experience. Operators, deep reaction chains, strategic sacrifices. Equal numbers refuse to merge until you spark them with a +. They need a little drama. Relatable.
• ZEN — no clock, no operators, no pressure. Just you, the void, and pleasantly wobbly arithmetic. Unlocked after your first Classic run.
• TIME ATTACK — the clock is permanently dying and only merging can save it. How long can you keep it alive?
• ECLIPSE — the endgame. Charge powers, store three of them, and fuse them into one of seventeen secret Ultimates. The rarest one opens an actual black hole that devours your entire board and hands back one enormous number. We are unreasonably proud of this.

WHAT MAKES IT DIFFERENT
• Liquid visuals — numbers that flow, stretch and fuse like living glass, rendered in real time. Yes, your phone can do this.
• Math-constant powers — reorder the ring with φ, gather with π, surge with e, sweep with Σ, transcend with ∞.
• A challenge constellation — dozens of goals that unlock modes, badges and rewards.
• An original ambient soundtrack — every merge chimes in harmony with the music.
• Arcade-style leaderboards for every mode. Three letters, immortal glory.

FREE AND FAIR
DOUBLE IT is free. Optional rewarded videos can grant an extra power-up — or summon the black hole for a second chance when a run ends. Always your choice, never required, and everything can be earned without watching a single ad.
