Pro Tips & Strategies

Want to climb the leaderboard instead of just surviving? Try these:

• Merge from the bottom up. Keep large orbs anchored at the bottom and let smaller ones stack above. This prevents awkward gaps that kill your board space.
• Set up chain reactions. Instead of merging immediately, arrange orbs so one drop triggers multiple merges at once. Combos are where the big scores hide.
• Don't hoard low-tier orbs. It's tempting to save them, but clearing clutter early keeps your grid flexible for the next big merge.

These three habits separate casual players from the ones pulling off 50-merge streaks.
