Mathstack vs Black Hole Galaxy

Mathstack - Sequence Puzzle Love number puzzles? This one's different. Stack your way to victory by building sequences from 1 to 15 (or 15 to 1) across five colorful stacks to clear the board. The catch? There are more cards than space on the board. Think ahead, use your temporary slots wisely, and plan your moves to uncover the cards you need. Three difficulty levels to match your mood: - Easy (1-5) for a quick brain break - Medium (1-10) for a solid challenge - Hard (1-15) for number-crunching pros Simple to learn. Tricky to master. Impossible to put down. Terms of Service: https://hazerim.com/terms-of-service/ Privacy Policy: https://hazerim.com/mathstack/privacy-policy/

You are a black hole. Everything else is food. Start barely big enough to swallow an asteroid. Drift through space eating debris, astronauts, rockets and fleeing spaceships — and every bite makes you bigger. Grow enough and the planets stop being scenery and start being lunch. Grow enough after that, and you swallow a star. But you are not the only hole out there. Rival black holes hunt the same field, and anything larger than you will eat you without hesitation. FEATURES • 100 handcrafted levels with escalating objectives • Endless mode — unlocked by beating level 50 • 20+ black hole skins, from simple colours to shaped holes, shockwave rings and living flame • Rival AI holes that flee what they fear and chase what they can catch • Boost to run down escaping ships — but boosting burns your own mass • Permanent upgrades: speed, growth, boost, coin gain, head start • One-thumb controls, portrait, playable offline Simple to start. Genuinely hard to finish.
