Halloween Edition: a swaying spider, cobwebs and friendly ghosts. A calm, ad-free ball sort puzzle.
Kolba is a calm ball sort puzzle. One new puzzle every day, the same one for everyone, plus as many extra boards as you like.
Move balls between glass tubes until every colour sits in a tube of its own. A group of the same colour on top moves together. Some puzzles add a jar: it holds one group at a time, locks to the first colour you put in it, and has to be empty when you finish. That one rule changes how you plan.
• 300 numbered chapters: finish one and the next is a tap away, from three colours up to eight
• Soft music, off in Settings
• A new daily puzzle at midnight, the same for everyone, easiest on Monday
• Free play at the size you choose: easy, like today, or hard
• Race a friend on the same board with a link, no account needed
• A short tutorial that teaches by playing, not by reading
• Hints that nudge before they tell, and undo as far back as you like
• A score from your moves against par, with no timer on the daily
• A quiet month view of the days you played, with no streak to lose
• Ball palettes and backgrounds to suit your eyes
• Colour-assist symbols, high contrast, reduced motion and VoiceOver support
• Optional Game Center leaderboards and achievements
• Optional iCloud sync of your lessons and finished days
• A widget, a Control Center control and a Siri shortcut for today's puzzle
• In English, Turkish, Spanish, Portuguese, French, German, Hindi, Russian and Indonesian
No ads. No purchases. No account. No tracking. Kolba works fully offline. Nothing goes to us: iCloud sync goes to your own iCloud, Game Center only if you turn it on, and a race link only when you share it.

Halloween Edition
• A spider swaying on its thread on Home, webs in the corners, a faint moonlight and friendly ghosts that come and go
• Think for a while and webs spin in from the board's corners while ghosts drop by; your next touch clears them
• Finish a puzzle and a spider strolls past
• Friend race links are now much shorter
• Turn it all off with 'Seasonal decorations' in Appearance
