Daily Double: the two cubes everyone plays

Daily Double is Flood Cube's main mode and the one the daily habit is built on. Each day it deals two cubes, generated from that day's date, so every player in the world gets exactly the same pair. There is no personalisation and no difficulty adjustment — if your friend beat it in 31 moves, they solved the identical puzzle you are looking at. It is free for everyone, guests included, every day of the week.

The two configurations

Cube	Grid per face	Colours	Cells	Par
First	8×8	8	384	43 moves
Second	9×9	9	486	50 moves

Both are plain colour cubes: no blockers, no powerups, nothing but colours and the move budget. The second cube unlocks once the first is finished — win or lose, you still get to play it.

Why the second cube is harder than it looks

On paper the step from 8×8 to 9×9 looks small. It isn't. The cell count rises 27% (384 to 486) and the colour count rises from 8 to 9, while Par only rises 16% (43 to 50). Those two changes work against you in different ways:

More cells means a longer journey. Your flood has to travel further across every face before the last corner falls.
More colours means every single capture is smaller. With nine colours instead of eight, a randomly chosen cell is less likely to match any colour you pick, so the average move grabs a thinner slice. This is the dominant effect, and it is why colour count matters more than grid size in Flood Cube — the same relationship shows up right across the difficulty table.

Practical consequence: budget your attention, not just your moves. Most players lose the second cube not because they ran out of ideas but because they spent the first fifteen moves on autopilot.

How to play the pair

Treat the first cube as reconnaissance. Because the pair is generated from the same daily seed, the colour palette is the same for both, and the first cube tells you which colours are abundant and which are scarce — information that transfers straight to the second. Then slow down. A useful rhythm:

Open wide. For the first handful of moves, take the largest captures available and get your region touching as many faces as possible. Early breadth is cheap; late breadth is expensive.
Rotate every turn. The screen shows you at most three faces. A colour that looks small from the front may be your biggest gain on the far side — cross-face adjacency is the mechanic most new players under-use.
Mid-game, count frontier variety. Between two similar captures, prefer the one whose new border touches more distinct colours. That keeps your later moves large.
Endgame backwards. Once four or five colours remain, plan from the colours left on the board rather than the biggest blob. Sparse colours scattered over several faces are cheap to collect at the end and expensive to chase early.

The full reasoning behind these, with worked examples, is in the Strategy Guide.

Streaks, exactly

The Daily Double streak counts days on which you won at least one cube. Win today and your streak increases if your previous win was yesterday; if your last win was older than that, the streak restarts at 1. A day that ends with no win at all resets it to zero. Streaks are tracked per mode, so your Daily Double streak and your Challenge Cube streak run independently — losing one does not cost you the other.

Two things worth knowing. Signing in (free) makes the streak durable across devices and browsers; as a guest it lives only in that browser's storage. And your progress inside a cube is saved as you play, so a closed tab, a dead battery or a refresh drops you back where you were rather than costing you the day.

Leaderboard

Because everyone plays identical cubes, the daily leaderboard is a straight comparison on move count. That is also why the mode is worth playing carefully rather than quickly — there is no clock in Daily Double, and nothing rewards rushing.
