Features
Read full description

Drop, squish and merge. ASTRA MERGE is a falling-and-merging puzzle with little smiling slimes. Enjoy soft motion and chains against waterside scenes and mythical temples. DROP AND MATCH Tap to drop one slime. Hold for continuous drops and move your finger sideways to aim. Slimes of the same tier merge on contact and grow to the next tier. Manage the pile before the same slime stays on the danger line too long. FOUR SHAPES, NINE TIERS Round, shallow cloud, rounded square and elongated slimes deform as they stack. Grow from transparent slimes to gold and rainbow, with moving eyes, blinks and changing expressions under pressure. MERGE RAINBOWS, CHANGE THE SCENE Merging two rainbows advances the STAGE. Enjoy nine mythical landscapes, merge effects and chains while improving your best MATERIALS score. PLAY AT YOUR PACE Your board and drop queue are saved on your device so you can resume later. Game Center is optional. Connecting lets you submit your best score to the world ranking and the supported Japan participation ranking. AGE BANDS, THREE TRIALS AND A ONE-TIME PURCHASE Ads and Game Center communication are disabled for users under 16 or whose age is unanswered. This device allows three new trial runs in total; resuming a saved board does not use a trial. Further new runs require the guardian explanation to be acknowledged and an Apple-verified one-time purchase. Acknowledgment does not verify guardian identity. Users aged 16+ without restricted history can play normally without buying. One non-consumable purchase skips revival video ads and lets you remove one chosen slime to continue. Purchases and ads share a total of three revivals per run. No monthly fees or automatic renewal. Check the actual price in Apple’s purchase sheet; purchases can be restored. Age-related ad and ranking restrictions remain after purchasing. Eligible users aged 16+ may see banner ads and choose a revival video when available. Purchasing does not remove banners. Ads follow age restrictions, current consent status and availability. Where required, you can consent, refuse or manage choices and change them in settings. Adjust sound, music, haptics and participation region in Settings. Privacy information, use and disclaimer, music credits and the support form are also available there. Deleting and reinstalling the app requires a fresh age choice, without carrying over age or restricted history. Trial usage and Apple purchase ownership remain separate. Normal updates keep your age choice.
