The free to play match 3 game literally can't survive without the energy and booster mechanics. If there's no energy mechanic, people WILL pay continuously and never pay a cent, leaving ingame ads as the only way to get revenue. But they don't tend to have the huge variety in level mechanics that your typical modern one has. Many earliest match 3 games were buy to play, like Jewel Quest. You are pretty much looking for something like, say, Fishdom, but with no lives and no boosts, and no frigging impossible without boosts levels.
They have to make their money somehow, and the only way anyone every buys boosts is if there are levels that are near impossible to beat with limited energy and no boosts. I presume the OP is looking for a game with a large number of levels, infinite energy, and no way to buy boosts.
