Drill Poker's materials and trainers are intended for persons 18 and older. The site itself runs no real-money games: the trainers are free and take no bets. But we link to poker rooms where real money is played, so we want to say the following.
Poker is a game of skill over the long run, but any single session is heavily influenced by chance, and losing is a normal part of it. Play only with money you can afford to lose, and keep your bankroll separate from living money.
Signs the game has stopped being entertainment
You play with money set aside for something else; you move up stakes to "win it back"; you hide the scale of your play from people close to you; you borrow to deposit; the game interferes with work or sleep. Any one of these is a reason to stop.
What you can do
Most rooms have self-limitation tools: deposit limits, time-outs and self-exclusion, available in account settings or via support. Simple rules work too: a fixed session length, a stop-loss, and no depositing on tilt.
Where to get help
Free, anonymous support in English, Russian and other languages is provided by Gambling Therapy (chat and support programs), and Gamblers Anonymous groups operate worldwide. If gambling is harming you or someone close to you, it's a solvable problem — reaching out works.
