DogeGamer.swapBack() (contracts/DogeGamer.sol#566-609) sends eth to arbitrary user
Dangerous calls:
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (contracts/DogeGamer.sol#592)
- (successs) = address(buybackFeeReceiver).call{gas: 30000,value: amountBNBDividend}() (contracts/DogeGamer.sol#594)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

DogeGamer.isOverLiquified(uint256,uint256) (contracts/DogeGamer.sol#771-773) uses timestamp for comparisons
Dangerous comparisons:

DividendDistributor.process(uint256) (contracts/DogeGamer.sol#291-315) has costly operations inside a loop:
- currentIndex ++ (contracts/DogeGamer.sol#312)
Use a local variable to hold the loop computation result.

Additional information: link

DogeGamer.swapThreshold (contracts/DogeGamer.sol#435) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 200
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Additional information: link

solc-0.8.5 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in DogeGamer.swapBack() (contracts/DogeGamer.sol#566-609):
- (success) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (contracts/DogeGamer.sol#592)
- (successs) = address(buybackFeeReceiver).call{gas: 30000,value: amountBNBDividend}() (contracts/DogeGamer.sol#594)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable DogeGamer._allowances (contracts/DogeGamer.sol#393) is not in mixedCase
Follow the Solidity naming convention.

Variable IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountADesired (contracts/DogeGamer.sol#152) is too similar to IDEXRouter.addLiquidity(address,address,uint256,uint256,uint256,uint256,address,uint256).amountBDesired (contracts/DogeGamer.sol#153)
Prevent variables from having similar names.

DogeGamer.slitherConstructorVariables() (contracts/DogeGamer.sol#378-778) uses literals with too many digits:
- distributorGas = 500000 (contracts/DogeGamer.sol#432)
Use: Ether suffix, Time suffix, or The scientific notation

DogeGamer._totalSupply (contracts/DogeGamer.sol#389) should be constant
Add the constant attributes to state variables that never change.

getUnpaidEarnings(address) should be declared external:
- DogeGamer.getUnpaidEarnings(address) (contracts/DogeGamer.sol#754-756)
Use the external attribute for functions never called from the contract.
