River Crossing IQ

River Crossing IQ has been rebuilt from the ground up. Travel with Sen through small villages, gardens and surprising puzzles. Observe the clues, try an idea and discover the next step at your own pace. Explore 42 levels across seven chapters: plan river crossings, measure water, arrange numbers, connect paths, guide messenger birds and roll a stone across the lotus pond. Each puzzle includes a story, illustrated rules and guidance when you need it. All levels and Solve with Sen are free to play, including offline. Choose English or Vietnamese, undo a move and continue from automatically saved progress. Optional Game Center and iCloud support can restore puzzle progress on another Apple device; when saves conflict, you choose which one to keep. Stars unlock optional specific hints. Earn stars through play, choose rewarded ads when available, or buy a star pack. A one-time purchase removes automatic ads; voluntary rewarded ads remain optional. The first level has no automatic ads. Already removed ads in an earlier version? Use Restore purchases with the same App Store account and ad removal comes back. Players of the earlier version receive a welcome gift of hint stars. No registration is required to play or purchase. Open Shop & Star wallet to purchase directly through the App Store. Signing in is optional. Guest and signed-in wallets remain separate; signing out returns to the guest wallet on this device. Consumable stars cannot be restored from store purchase history. Guest stars remain with the guest wallet on this device; signed-in stars remain with that wallet account. Open Shop & Star wallet while online and wait for synchronization before clearing app data or changing devices. Questions or something missing from the earlier version? Contact [email protected].
