Numtiva is currently in development and testing. A Google Play link will appear here when it is ready.
Core level puzzles and on-device progress work offline. Ads and any enabled online services require an internet connection.
10 free attempts reset at midnight in the Europe/Istanbul time zone. Resuming the same active attempt does not spend another credit. Extra rewarded-ad credits carry over.
The new version includes a connection for RemGame-hosted cloud saves and weekly competitions. Live availability depends on HTTPS and account setup. Google sign-in becomes available after Google configuration is completed. An account is optional for the core game.
No. Practice has unlimited time and mistakes and uses no daily play credits. It grants no campaign stars, coins or daily streak progress.
A verified account creates an invitation code valid for 48 hours. Two players solve the same three puzzles asynchronously. Each round lasts two minutes and uses one play credit. Scores are verified on the server. Live play requires completed HTTPS and account setup.
5000 levels span 50 worlds. Later levels increase number ranges and empty cells while reducing the time budget. Every tenth level offers a short breather; world endings have special finals.
