A responsible player approaches gambling consciously and keeps the game under control. The idea is to hold the damage from excessive play to a minimum and not to let addiction take root.
The operator contributes through what §§ 13 to 16 of Act No. 186/2016 Coll. require of it: every operator, TRELANGEN a.s. included, must make tools and information for safe play available to players, namely financial and time limits, guidance on risks and on self-exclusion, and measures shielding minors. Tools only work, though, when the player uses them, which is why it pays to watch your own behaviour and not to overlook warning signs.
