Score Four 3D: 4 in a Row

Four in a row was easy. Now the board goes up.

Score Four: 3D Arena is a 3D four in a row board game played on a 5x5x5 grid of light. Drop a disc, it stacks on a glowing beam, and four in a row counts in ANY straight line - flat rows, vertical columns, and diagonals that climb through all five layers. Thirteen directions to win. Thirteen to lose. Most players only ever watch three of them.

A flat 4 in a row board has 69 winning lines. This one has 302.

ONLINE MULTIPLAYER - NO ACCOUNT, NO SIGN-UP:
Play online against a real person in seconds. Quick Match finds you an opponent, or invite a friend with a room code or a share link and play online together from anywhere. No email, no password, no login wall. Every match is ranked.

PLAY OFFLINE VS. THE COMPUTER:
Four AI difficulty levels, from a casual opponent to a Master that searches ahead and punishes lazy moves. The offline single player mode needs no internet - good for practice, flights and dead zones.

2 PLAYER ON ONE DEVICE:
Pass-and-play four in a row for two players sharing one phone or tablet. The oldest multiplayer mode there is, still undefeated.

HOW TO PLAY:
Tap a beam of light to drop your disc. It falls to the lowest free slot, exactly like the classic board game. First player to line up four discs in any of the thirteen directions wins. Drag to orbit the board, pinch to zoom, and snap to Top View when the grid gets crowded. Easy to learn in one game. Considerably harder to master.

A 3D BOARD YOU CAN ACTUALLY READ:
This is a real 3D strategy board game, not a flat one with a drop shadow. The whole arena is rendered in neon and you can look at it from any angle, mid-game, without losing your place.

DAILY CHALLENGES AND PUZZLES:
A new four in a row puzzle every day. Solve it, earn Grid Points, unlock discs and arenas. Come back tomorrow for a harder one.

EARNED, NEVER SOLD:
Every rank, skin and arena is unlocked by playing. No paywalls, no loot boxes, no energy timers. The game is free to play with ads, and one optional purchase removes them for good.

WHY THE THIRD DIMENSION CHANGES EVERYTHING:
On a flat board you defend sideways and up. Here a threat can arrive from above, below or along a diagonal that cuts through three layers of the cube. Blocking one line often builds another. Strong players learn to set two traps at once on two different planes - and the Master AI already knows that trick.

ALSO INCLUDED:
- Win, loss and draw stats plus full move history
- Ranks, unlockable disc skins and alternate neon arenas
- Haptics and a synth soundtrack of satisfying drop notes
- Reduced motion and low-glow mode for light-sensitive players
- Phone and tablet support
- Online multiplayer and offline play, no subscription

WHO THIS IS FOR:
Anyone who grew up on four in a row, gomoku, or 3D tic tac toe and wants a harder version. If you like abstract strategy games, board games you can play online with friends, or a daily brain puzzle, the 5x5x5 grid will keep you honest.

Score Four: 3D Arena - a 3D strategy board game for anyone who thought four in a row was solved.
