ONE POSSIBLE RUN
An example buildSTAGE 01 / 04
Get a head start.
This run starts with Correct Lines Start. Use the prefilled correct lines to get moving on the first puzzle.
Your build for this stage
- Correct Lines Start
Some correct lines are placed at the start.
STAGE 02 / 04
Your first pick opens an upgrade.
Because you picked Correct Lines Start, Lv2 can now appear. This time, upgrade your head start instead of adding another effect.
Your build for this stage
- Correct Lines Start Lv2
Lv2 replaces the original buff with a stronger head start.
STAGE 03 / 04
Add clues to your head start.
Pick Extra Hints Start next. It reveals hidden numbers alongside the correct lines from the Lv2 buff you carried forward.
Your build for this stage
- Correct Lines Start Lv2
- Extra Hints Start
Correct lines plus extra clues. Two effects for the next puzzle.
STAGE 04 / 04
Bring your build to the final stage.
Finish with Board Size Reduction. Keep your lines and clues, take on a smaller board, and aim for a faster total time.
Your build for this stage
- Correct Lines Start Lv2
- Extra Hints Start
- Board Size Reduction
Your existing effects plus a smaller board for the final stage.
Add the clear times of all 4 stagesOne total time. The monthly leaderboard.
An illustration of one possible build, not the actual game UI or a simulated draw. Buffs are offered at random; this combination is not guaranteed.
Turn an early pick into a stronger build.
Carry buffs into the next stage. Pick Correct Lines Start and its upgrade can appear later. Add a different effect, or strengthen what you already have?
Take a pick. Or take another chance.
The buff you want may not appear. With limited rerolls, decide whether to redraw the three choices or make the most of the options in front of you.
Give up your build to skip a stage?
With Buff Reroll Increase, Stage Skip can appear in stages 2 and 3. It lets you skip a stage, but costs you every buff you have collected so far.
Higher-tier buffs become more likely in later stages. One daily attempt as standard; additional attempts cost 100 SP. The Legend plan includes five daily attempts and unranked training.
