Drop, double, chain & climb
Only for iPhone

iPhone
Drop, double, chain. Today’s shared 50-drop board is free, plus 3 free Classic runs a day. Nine rungs to climb and chains you set up yourself. No ads.
Drop a number. Set off a chain. Climb to Orbit.
Only the bottom rungs ever fall. Drop a number into one of five columns, watch equal numbers double where they touch, and let gravity chain one merge into the next — climbing 2 Pebble all the way to 512 Orbit.
NO ADS. NO LIVES. NO BOOSTS.
No ads, no consumable lives to wait out, and nothing you can buy to raise a score. Pro is a one-time unlock or a Play Pass — or nothing at all.
PLAN THE CLIMB
See the piece in hand and the next two pieces before you commit. Choose a column, set up connected matches, and build chain reactions that can transform the whole board.
ONE SHARED DAILY
Every player starts with the same Daily seed and 50-drop rules. Later pieces respond to your climb, so planning the ladder matters.
16 FIXED CHALLENGES
Learn Upward through four chapters of authored, repeatable boards. The four-stage Trailhead chapter is free. Pro opens Ridgecraft, Thin Air, and Orbit School, with XP and board-theme rewards along the way.
FIVE WAYS TO PLAY
• Daily Climb — the shared 50-drop board
• Classic — an open climb to Orbit
• Blitz — two minutes, no take-backs
• Chain Hunt — 50 drops with bonus points for deep cascades
• Rising Sky — safe board space contracts every 10 drops
BUILT TO FEEL GOOD
Number-first tiles stay readable across every theme. Landing feedback, escalating haptics, rising chain tones, danger states, and a full Orbit celebration make every important move clear.
WHAT FREE INCLUDES
Free players receive the full Daily Climb, the Daily and Classic leaderboards, three Classic starts per day, the four-stage Trailhead, missions, achievements, and recent local progress. Upward Pro adds unlimited Classic, three specialty modes, 12 advanced challenges, 500-run history, two years of Daily archives, the Blitz leaderboard, friend challenges, Daily history sync, and two more board themes.
