Correct spelling, explanation: both binging and bingeing are acceptable, according to dictionaries. It may seem surprising because many present participle forms in English are created by dropping the silent -e at the end of a verb and only then adding the -ing suffix. However, around 1980, retaining the -e became distinctly more popular than dropping it. You can correctly choose bingeing or binging, but the first one is primarily used in Great Britain and the other in America.
