LAS VEGAS (AP) — Nevada casinos rode a robust rebound from coronavirus restrictions in June, taking in more than $1 billion in winnings for the fourth straight month and nearly reaching the all-time record set a month earlier. But a spike in COVID-19 cases since mid-May — and the restoration of indoor mask mandates beginning Friday — could cloud the July outlook in an economy heavily reliant on tourism and gambling. State regulators said Thursday that casinos reported house winnings of nearly $1.2 billion statewide during the month. For the fiscal year ending June 30, casino winnings were up 14% compared with pandemic-battered fiscal 2020.
