BubbleTots
A fill-the-potion game for ages 3–5: draw bubbles from a see-through bag to fill Bub’s potion. Draw another for more — or pour what you’ve got in to keep it safe. A 💥 pop only spills HALF your bubbles this round (never all, and never your potion), so it’s always gentle. The keep-going-or-stop choice, felt through play. No losing. On-device; nothing leaves your device.

Meet the cast
BubbleTots has a tiny friendly crew who make push-your-luck something a three-year-old can hold: Bub the bubble-mixer draws bubbles and decides "one more, or pour it in?"; the Bag is the see-through source you draw from (its pops countable); Pop the fizz is the gentle risk (it spills HALF the round-jar, never the potion); and the Potion is the goal you fill to the top (their illustrated storybooks are on the way).
Bub
the bubble-mixer — draws bubbles and decides one-more-or-pour (the push-your-luck choice: risk vs bank)
the Bag
The see-through source — you can count the bubbles and the pops still inside (composition-probability from the inside)
Pop
The gentle risk — a 💥 pop spills HALF this round’s bubbles, never all and never the banked potion (risk that never ruins)
the Potion
The goal — poured-in bubbles are safe forever; fill it to the top to win (bank-what-you-keep)
