DigiTalis: Math Bubble Game
Catch, Solve, Stay Afloat
Free · Designed for iPad. Not verified for macOS.
New in 1.1: two fresh looks, Tidepool and Deep Current, plus livelier water and an overflow warning. Four modes from simple addition to full PEMDAS, fully offline.
Numbers and operators fall from the top of the screen. Catch them, drag them into place, and build an equation that hits the target before the water rises too high. DigiTalis turns arithmetic practice into a fast, hands-on bubble game for anyone who wants to sharpen their math skills.
Pick a target number, then tap or drag falling bubbles into your equation tray. Swap digits, cycle through operators, and use parentheses to control order of operations. Solve it correctly and the water drops back down; let the tray run dry or the water reach the top and the round ends.
FEATURES
• Four difficulty modes: Addition (+ −), Arithmetic (+ − × ÷), PEMDAS Easy, and PEMDAS Hard with parentheses and larger targets
• Three bubble fall speeds — Slow, Medium, and Fast — so beginners and experts can both find their pace
• Step-by-step interactive tutorial that teaches bubble selection, operator switching, and parentheses before you play for real
• Two operator input styles: cycle through operators with a tap, or choose from a popup menu
• Two looks: bright Tidepool and dark Deep Current, or match your phone's appearance
• Rising-water challenge with splashing bubbles, a moving water surface, an overflow warning, and an underwater game-over sequence
• Personal high scores tracked separately for every difficulty and speed combination
• Sound effects for catching bubbles, correct and incorrect answers, and level transitions
• Runs entirely on your device — no account, no ads, and no internet connection required
• Full iPad support with proportional scaling across all screen sizes and orientations
DigiTalis is built for students practicing addition, multiplication, and PEMDAS order of operations, for teachers who want a quick warm-up activity, and for anyone who enjoys a quick mental-math challenge. Start with Addition mode to learn the controls, then work up to PEMDAS Hard for a real test of speed and accuracy.
Because everything happens locally on your device, there is nothing to sign in to and nothing to configure — just pick a mode and start solving.
Ratings & Reviews
New in DigiTalis 1.2.1:
• Hungry fish: bubbles that splash below the water line become a snack, and the nearest fish swims over to gulp them down.
• Fixed PEMDAS Hard rejecting equations that use ^ as invalid.
• The speed picker no longer looks like Medium is pre-selected. The speed you tap lights up before the game starts.
