Double Down is a sliding-merge puzzle on a four-by-four table of casino chips. Every move slides every chip as far as it will go in one direction, and two chips of the same value that collide become one chip worth double. A new chip lands after each move, so the table fills whether you are making progress or not. The run ends when it is full and no two neighbours match. There is no undo and no pause: each move commits the whole table.
Controls
| ← ↑ ↓ → | Slide the whole table |
|---|---|
| W A S D | The same four directions |
| Enter | Deal a new table |
| R | Restart |
Touch: Swipe the board in any direction. Taps do nothing during a run, so a mis-tap cannot move the table.
Tips
- Pick a corner and keep your biggest chip in it. Every move slides everything, so a big chip that wanders into the middle splits the table in two.
- Slide in only three directions and you will rarely be forced. The fourth direction is what puts a new chip somewhere you did not want one.
- Points come from what a collision makes, not from how many you make, so one 512 is worth as much as every merge that built it.
- Four collisions in one move is worth chasing: line up two matching pairs on the same row before you slide.
- A new chip is a 4 one time in ten. That is what breaks an otherwise tidy table, so leave more room than you think you need.
