Todo Number Matrix – Todo Number Matrix: Brain teasers, logic puzzles, and mathematical reasoning for kids Review

No sound. No tech support. No refund. Big mistake, bought the bundle and none of the apps have sound. WASTE OF MONEY. PS. TECH support told me to turn the sound on five times......thanks for nothing.
