Digi Chompers

DigiChompers is a math-practice game for kids ages 5 through 12. Move Digi — the green pixel chomper with the big orange hands — across a 5×5 grid, chomp the correct answer, dodge the Chompers, level up.

18 LEARNING MODES across six grade tiers

• K-1st, 2nd, 3rd, 4th, 5th, 6th+ (with accurate Common Core-aligned problem ranges per grade)
• Addition, Subtraction, Multiplication, Division
• Factors, Rounding, Place Value, Greater/Less Than
• Fractions, Decimals, Percents

ADAPTIVE DIFFICULTY Every kid profile has its own rolling performance window. Tier up when the kid is acing 80%+ fast enough; hold when they're working through it; tier down gently when they're struggling. Silent to the kid (nothing pops "LEVEL DOWN!" ever), loud to the parent in the Parent Zone dashboard.
