Take on the daily challenge and compete for the best total time on the monthly leaderboard.
ONE POSSIBLE RUN
An example buildSTAGE 01 / 04
This run starts with Correct Lines Start. Use the prefilled correct lines to get moving on the first puzzle.
Your build for this stage
Some correct lines are placed at the start.
STAGE 02 / 04
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
Lv2 replaces the original buff with a stronger head start.
STAGE 03 / 04
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 plus extra clues. Two effects for the next puzzle.
STAGE 04 / 04
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
Your existing effects plus a smaller board for the final stage.
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.
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?
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.
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.
