Chip packs are optional in-app purchases that add extra virtual chips to your balance. They are a convenience for players who want a bigger stack quickly, but they are never required — the daily bonus and rewarded ads keep you supplied for free. Importantly, chip packs only give you virtual chips for play; the chips have no real-money value, cannot be cashed out, and buying them is not a bet or a deposit toward winnings. Purchases are handled securely through the app store's billing. If you would rather remove ads and add cosmetics instead, VIP is a separate optional extra.
