Had to update review. This is F2P, but has HUGE paywall to advance in rank, you NEED to COIN to advance in top 100 rank to gain LIS rewards. Every level, you gain 0.0+ LIS, but STOPS at level 50. You gain 0.0+ LIS for daily tasks, but TOO small to matter. Coiners get 2k% chance in win jackpot, 1/10M chance for F2P players. Believe me, I've grinded hard, but you just CAN'T advance in top 100 to get LIS rewards without coining. Heck, now at level 50, but ONLY got 20 LIS from their 2 merge games
