Full of games or playfulness; characterized by gaming or having the quality of a game.
Compound: 'game' + '-ful' (suffix meaning 'full of'). A relatively modern construction reflecting contemporary language-building patterns.
Video game designers use 'gameful' design to make non-game activities more engaging—apps use points, badges, and leaderboards to make boring tasks feel like games, which is why people suddenly enjoy their exercise routines.
